異常現象 Troubleshooting Guide
Motor Rotates in One Direction Only (馬達僅在一個方向上旋轉)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| The drive prohibits reverse rotation. (驅動器禁止反向旋轉。) | Check parameter b1-04. (檢查參數 b1-04。) Set the drive to allow the motor to rotate in reverse (b1-04 = “0”). (將驅動器設置為允許馬達反向旋轉 (b1-04 = “0”)。) |
| A Reverse run signal has not been entered, although a 3-Wire sequence is selected. (雖已選擇三線制順序，但未輸入反向運轉訊號。) | Make sure that one of the input terminals S3 to S7 for the 3-Wire sequence has been set for reverse. (確保已為三線制順序設置了輸入端子 S3 到 S7 中的一個以用於反向。) |
Motor Is Too Hot (馬達過熱)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| The load is too heavy. (負載過重。) | If the load is too heavy for the motor, the motor will overheat as it exceeds its rated torque value for an extended period of time. (如果負載對馬達來說過重，馬達將因超過其額定扭矩值而長時間過熱。) Keep in mind that the motor also has a short-term overload rating in addition to the possible solutions provided below: (請記住，馬達除了下面的可能解決方案外，還有一個短時過載額定值：)
|
| The air around the motor is too hot. (馬達周圍的空氣過熱。) | Check the ambient temperature. (檢查環境溫度。) Cool the area until it is within the specified temperature range. (將該區域降溫至指定的溫度範圍內。) |
| The drive is operating in a vector control mode but Auto-Tuning has not yet been performed. (驅動器在向量控制模式下運行，但尚未執行自動調諧。) | Perform Auto-Tuning. (執行自動調諧。) Calculate the motor value and reset the motor parameters. (計算馬達值並重置馬達參數。) Change the motor control method to V/f Control (A1-02 = “0”). (將馬達控制方式更改為 V/f 控制 (A1-02 = “0”)。) |
| Insufficient voltage insulation between motor phases. (馬達相間絕緣不足。) | When the motor is connected to terminals U/T1, V/T2, and W/T3, voltage surges occur between the motor coils and drive switching. (當馬達連接到端子 U/T1, V/T2, 和 W/T3 時，馬達線圈和驅動器開關之間會產生電壓浪湧。) Normally, surges can reach up to three times the drive input power supply voltage (600 V for 200 V class, and 1200 V for 400 V class). (通常，浪湧可達驅動器輸入電源電壓的三倍（200 V 等級為 600 V，400 V 等級為 1200 V）。) Use a motor with voltage tolerance higher than the max voltage surge. (使用耐壓高於最大電壓浪湧的馬達。) Use a motor designed to work specifically with a drive when using a 400 V class unit. (使用專為搭配驅動器設計的馬達，特別是在使用 400 V 等級單元時。) Install an AC reactor on the output side of the drive. (在驅動器的輸出側安裝一個交流電抗器。) |
| The motor fan has stopped or is clogged. (馬達風扇停止或堵塞。) | Check the motor fan. (檢查馬達風扇。) |
Drive Does Not Allow Selection of Rotational Auto-Tuning (驅動器不允許選擇旋轉式自動調諧)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| The drive is in the incorrect motor control method for Rotational Auto-Tuning. (驅動器處於不正確的馬達控制方式下，不適用於旋轉式自動調諧。) | Check if the drive is set to V/f Control by accident (A1-02 = 0). (檢查驅動器是否意外設置為 V/f 控制 (A1-02 = 0)。) Change the motor control method to Open Loop Vector Control (A1-02 = “2”). (將馬達控制方式更改為開環向量控制 (A1-02 = “2”)。) |
Motor Hunting Occurs at Low Speeds (馬達在低速時發生抖動)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| Excessive load inertia in Open Loop Vector Control. (開環向量控制中的負載慣量過大。) | Excess load inertia can cause motor hunting in Open Loop Vector Control due to slow motor response. (過大的負載慣量可能因馬達響應慢而在開環向量控制中導致馬達抖動。) Increase the speed feedback detection control time constant (n2-02) from its default value of 50 ms to an appropriate level between 200 and 1000 ms. Adjust this setting in combination with n2-03 (Feedback Detection Control Time Constant 2). (將速度回饋檢測控制時間常數 (n2-02) 從其預設值 50 ms 增加到 200 到 1000 ms 之間的適當水平。結合 n2-03 (回饋檢測控制時間常數 2) 調整此設定。) |
oPE02 Error Occurs when Lowering the Motor Rated Current (當降低馬達額定電流時發生 oPE02 錯誤)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| The user is trying to set the motor rated current in E2-01 to a value lower than the no-load current set in E2-03. (使用者正試圖將 E2-01 中的馬達額定電流設定為低於 E2-03 中所設定的無負載電流值。) | Make sure that value set in E2-01 is higher than E2-03. Setting E2-01 < E2-03 will trigger an oPE02 error. (確保 E2-01 中的值高於 E2-03。設定 E2-01 < E2-03 將觸發 oPE02 錯誤。) |
| The motor rated current and the motor no-load current settings in the drive are incorrect. (驅動器中馬達額定電流和馬達無負載電流的設定不正確。) | If it is necessary to set E2-01 lower than E2-03, first lower the value set to E2-03, then change the setting in E2-01 as needed. (如果需要將 E2-01 設定得比 E2-03 低，請先降低 E2-03 的值，然後再根據需要更改 E2-01 的設定。) |
Overvoltage Occurs When Running at a Constant Speed (以恆定速度運行時發生過電壓)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| Excessive load inertia in Open Loop Vector Control. (開環向量控制中的負載慣量過大。) | Loads with a lot of inertia (fans, etc.) can trigger an overvoltage fault when operating in Open Loop Vector Control. (當在開環向量控制中運行時，具有大量慣量（例如風扇）的負載會觸發過電壓故障。) Switch to the V/f motor control method. (切換到 V/f 馬達控制方式。) Adjust the values set for the speed feedback detection control time constant (n2-02, n2-03). (調整速度回饋檢測控制時間常數 (n2-02, n2-03) 的設定值。) |
Motor Stalls During Acceleration or With Large Loads (在加速時或在負載較大時馬達停轉)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| Load is too heavy. (負載過重。) | Take the following steps to resolve the problem: (採取以下步驟來解決問題：) Reduce the load. (減輕負載。) Increase the acceleration time. (增加加速時間。) Increase motor capacity. (增加馬達容量。) Although the drive has a Stall Prevention function and a Torque Compensation Limit function, accelerating too quickly or trying to drive an excessively large load can exceed the capabilities of the motor. (儘管驅動器具有停轉預防功能和扭矩補償限制功能，但過快加速或試圖驅動過大的負載可能會超出馬達的能力。) |
Motor Will Not Accelerate or the Acceleration Time Is Too Long (馬達不加速或加速時間過長)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| Frequency reference is too low. (頻率參考過低。) | Check the maximum output frequency (E1-04). (檢查最大輸出頻率 (E1-04)。) Increase E1-04 if it is set too low. (如果設定過低，請增加 E1-04。) Check U1-01 for proper frequency reference. (檢查 U1-01 以獲取正確的頻率參考。) Check if a frequency reference signal switch has been set to one of the multi-function input terminals. (檢查是否已將頻率參考訊號開關設定為其中一個多功能輸入端子。) Check for low gain level set to terminals A1 or A2 (H3-03, H3-11). (檢查設定到端子 A1 或 A2 的低增益電平 (H3-03, H3-11)。) |
| Load is too heavy. (負載過重。) | Reduce the load so that the output current remains within the motor-rated current. (減輕負載，使輸出電流保持在馬達額定電流範圍內。) In extruder and mixer applications, the load will sometimes increase as the temperature drops. (在擠出機和攪拌機應用中，隨著溫度下降，負載有時會增加。) Check if the mechanical brake is fully releasing as it should. (檢查機械煞車是否正常完全鬆開。) |
| The torque limit function is operating in Open Loop Vector Control. (扭矩限制功能在開環向量控制中運行。) | Check the torque limit setting. It may be too low. (L7-01 through L7-04). (檢查扭矩限制設定。它可能設定得過低。 (L7-01 到 L7-04)。) Reset the torque limit to its default value (200%). (將扭矩限制重置為其預設值 (200%)。) |
| Acceleration time has been set too long. (加速時間設定過長。) | Check if the acceleration time parameters have been set too long (C1-01, -03, -05, -07). (檢查加速時間參數是否設定過長 (C1-01, -03, -05, -07)。) |
| Motor characteristics and drive parameter settings are incompatible with one another in V/f Control. (在 V/f 控制中，馬達特性和驅動器參數設定彼此不相容。) | Set the correct V/f pattern so that it matches the characteristics of the motor being used. (設定正確的 V/f 模式，使其與所用馬達的特性相匹配。) Check E1-03 (V/f Pattern Selection). (檢查 E1-03 (V/f 模式選擇)。) |
| The right combination of motor characteristics have not been set in Open Loop Vector Control. (在開環向量控制中，未設定正確的馬達特性組合。) | Execute Rotational Auto-Tuning. (執行旋轉自動調諧。) |
| Incorrect frequency reference setting. (頻率參考設定不正確。) | Check the multi-function analog input settings. (檢查多功能類比輸入設定。) Check if multi-function analog input terminal A1 or A2 is set for frequency gain (H3-02 or H3-10 = “1”). If so, the frequency reference will be 0 if there is no voltage (current) input provided. (檢查多功能類比輸入端子 A1 或 A2 是否設定為頻率增益 (H3-02 或 H3-10 = “1”)。如果是，如果沒有提供電壓（電流）輸入，頻率參考將為 0。) Ensure H3-02 and H3-10 are to the proper values. (確保 H3-02 和 H3-10 是適當的值。) Ensure the analog input value is set to the right voltage (U1-13, U1-14). (確保類比輸入值設定為正確的電壓 (U1-13, U1-14)。) |
| The Stall Prevention level during acceleration and deceleration set too low. (加速和減速期間的停轉預防等級設定過低。) | Check the Stall Prevention level during acceleration (L3-02). (檢查加速期間的停轉預防等級 (L3-02)。) If L3-02 is set too low, acceleration will take a fair amount of time. (如果 L3-02 設定過低，加速將需要相當長的時間。) Increase L3-02. (增加 L3-02。) |
| The Stall Prevention level during run has been set too low. (運行期間的停轉預防等級設定過低。) | Check the Stall Prevention level during run (L3-06). (檢查運行期間的停轉預防等級 (L3-06)。) If L3-06 is set too low, speed will drop as the drive outputs torque. (如果 L3-06 設定過低，隨著驅動器輸出扭矩，速度會下降。) Increase the setting value. (增加設定值。) |
| Although the drive is operating in Open Loop Vector motor control method, Auto-Tuning has not been performed. (儘管驅動器在開環向量馬達控制模式下運行，但尚未執行自動調諧。) | Perform Auto-Tuning. (執行自動調諧。) Calculate motor data and reset motor parameters. (計算馬達數據並重置馬達參數。) Switch to the V/f motor control method (A1-02 = “0”). (切換到 V/f 馬達控制模式 (A1-02 = “0”)。) |
| Drive reached the limitations of the V/f motor control method. (驅動器達到了 V/f 馬達控制模式的極限。) | The motor cable may be long enough (over 50 m) to require Auto-Tuning for line-to-line resistance. (馬達電纜可能足夠長（超過 50 公尺），需要對線間電阻進行自動調諧。) Be aware that V/f Control is comparatively limited when it comes to producing torque at low speeds. (請注意，V/f 控制在低速下產生扭矩方面相對有限。) Consider switching to Open Loop Vector Control. (考慮切換到開環向量控制。) |
Drive Frequency Reference Differs from the Controller Frequency Reference Command (驅動器頻率參考與控制器頻率參考命令不同)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| The analog input frequency gain and bias are set to incorrect values. (類比輸入頻率增益和偏差設定值不正確。) | Check the main speed frequency reference terminal input gain level assigned to terminals A1 and A2, as well as the frequency reference input bias to terminals A1 and A2 (parameters H3-03, H3-04, and H3-12). (檢查分配給端子 A1 和 A2 的主速度頻率參考端子輸入增益等級，以及分配給端子 A1 和 A2 的頻率參考輸入偏差（參數 H3-03、H3-04 和 H3-12)。) Set these parameters to the appropriate values. (將這些參數設定為適當的值。) |
| A frequency bias signal is being entered via analog input terminals A1 or A2. (透過類比輸入端子 A1 或 A2 輸入頻率偏差訊號。) | If multi-function analog input terminals A1 and A2 are set for frequency reference (H3-02 = 0 and H3-10 = 0), the addition of both signals builds the frequency reference. (如果多功能類比輸入端子 A1 和 A2 設定為頻率參考（H3-02 = 0 和 H3-10 = 0），則兩個訊號的總和構成頻率參考。) Ensure that H3-02 and H3-10 are set appropriately. (確保 H3-02 和 H3-10 設定適當。) Check the input level set for terminals A1 and A2 (U1-13, U1-14). (檢查端子 A1 和 A2 的輸入等級設定 (U1-13, U1-14)。) |
Poor Speed Control Accuracy (速度控制精度差)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| Drive reached the slip compensation limit. (驅動器達到滑差補償極限。) | Check the slip compensation limit (C3-03). (檢查滑差補償極限 (C3-03)。) Increase the value set to C3-03. (增加設定值 C3-03。) |
| Motor-rated voltage is set too high in Open Loop Vector Control. (在開環向量控制中，馬達額定電壓設定過高。) | The input voltage for the drive determines the maximum output voltage. A drive with an input of 200 Vac can only output a maximum of 200 Vac. Open Loop Vector Control sometimes calculates an output voltage reference value that exceeds the maximum drive output voltage level, resulting in a loss of speed control accuracy. (驅動器的輸入電壓決定了最大輸出電壓。輸入為 200 Vac 的驅動器最大只能輸出 200 Vac。開環向量控制有時會計算出超過最大驅動器輸出電壓等級的輸出電壓參考值，導致速度控制精度下降。) Use a motor with a lower voltage rating (a vector control motor). (使用額定電壓較低的馬達（向量控制馬達）。) Increase the input power voltage. (增加輸入電源電壓。) |
| Auto-Tuning did not complete properly for Open Loop Vector Control. (開環向量控制的自動調諧未正確完成。) | Perform Auto-Tuning again. (再次執行自動調諧。) |
Deceleration Takes Longer Than Expected with Dynamic Braking Enabled (啟用動態煞車後減速時間長於預期)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| L3-04 is set incorrectly. (L3-04 設定不正確。) | Check the Stall Prevention Level during deceleration (L3-04). (檢查減速期間的停轉預防等級 (L3-04)。) If a braking resistor option has been installed, disable Stall Prevention during deceleration (L3-04 = “0”). (如果已安裝煞車電阻選件，請停用減速期間的停轉預防功能 (L3-04 = “0”)。) |
| The deceleration time is set too long. (減速時間設定過長。) | Set deceleration to more appropriate time (C1-02, C1-04, C1-06, C1-08). (將減速時間設定為更適當的時間 (C1-02, C1-04, C1-06, C1-08)。) |
| Insufficient motor torque. (馬達扭矩不足。) | Assuming parameter settings are normal and that no overvoltage occurs when there is insufficient torque, it is likely that the demand on the motor has exceeded the motor capacity. (假設參數設定正常，且在有足夠扭矩時沒有發生過電壓，則馬達上的需求很可能已超過馬達容量。) Use a larger motor. (使用更大的馬達。) |
| Reaching the torque limit. (達到扭矩極限。) | Check the settings for the torque limit (L7-01 through L7-04). (檢查扭矩極限的設定 (L7-01 到 L7-04)。) If the torque limit is enabled, deceleration might take longer than expected because the drive cannot output more torque than the limit setting. Ensure the torque limit is set to a large enough value. (如果啟用了扭矩極限，減速可能比預期要長，因為驅動器無法輸出超過極限設定的扭矩。確保扭矩極限設定得足夠大。) Increase the torque limit setting. (增加扭矩極限設定。) If multi-function analog input terminal A1 or A2 is set to torque limit (H3-02 or H3-10 equals 10, 11, 12, or 15), ensure that the analog input levels are set to the correct levels. (如果多功能類比輸入端子 A1 或 A2 設定為扭矩極限（H3-02 或 H3-10 等於 10、11、12 或 15），請確保類比輸入電平設定為正確的電平。) Ensure H3-02 and H3-10 are set to the right values. (確保 H3-02 和 H3-10 設定為正確的值。) Ensure the analog input is set to the correct value. (確保類比輸入設定為正確的值。) |
| Load exceeded the internal torque limit determined by the drive rated current. (負載超過了由驅動器額定電流決定的內部扭矩極限。) | Switch to a larger capacity drive. (切換到更大容量的驅動器。) |
Motor Hunting Occurs When Operating With a Light Load (馬達在輕負載下運行時發生抖動)
| Cause (原因) | Possible Solutions (可能的解決方案) |
|---|---|
| Carrier frequency is too high. (載波頻率過高。) | Lower the carrier frequency setting C6-02. (降低載波頻率設定 C6-02。) |
| Large V/f setting value at low speeds triggers overexcitation. (低速時較大的 V/f 設定值觸發過激勵。) | Select the proper V/f pattern (E1-03). (選擇正確的 V/f 模式 (E1-03)。) Use parameters E1-04 through E1-10 to set the V/f pattern in relation to the load characteristics. (使用參數 E1-04 到 E1-10 來設定與負載特性相關的 V/f 模式。) |

(當輸出頻率大於 L4-01 中設定的頻率檢測等級時，多功能觸點輸出端子將會啟動。將 L4-01 設定在 1.0 到 3.0 Hz 之間。) Slipping may occur when stopping because hysteresis is used in Frequency Reference 2 (where the frequency agree setting in L4-02 is 2.0 Hz). To prevent this, change the setting to 0.1 Hz. (停止時可能會發生滑動，因為在頻率參考 2 中使用了磁滯（其中 L4-02 中的頻率同意設定為 2.0 Hz）。為防止這種情況，將設定更改為 0.1 Hz。) Do not use the multi-function contact output setting “During Run” (H2-01 = 0) for the brake signal.

|---|---|
| Exceeded 110% of the rated output current of the drive while operating at low speeds. (在低速運行時超過驅動器額定輸出電流的 110%。) | If the output current rises too high at low speeds, the carrier frequency automatically reduces and causes a whining or buzzing sound. (如果輸出電流在低速時上升過高，載波頻率會自動降低並發出尖銳或嗡嗡的聲音。) If the sound is coming from the motor, disable carrier frequency derating (L8-38 = “0”).

| The drive is not in Drive Mode. (驅動器不在驅動模式。) | A run command will not be issued. Exit to the Drive mode and cycle the run command. (不會發出運行命令。退出到驅動模式並循環運行命令。) |
| The frequency reference is too low. 頻率參考值過低。• If the frequency reference is set below the frequency set in E1-09 (Minimum Output Frequency), the drive will not operate. 如果頻率參考值設定低於 E1-09（最小輸出頻率）中設定的頻率，變頻器將無法運作。 • Raise the frequency reference to at least the minimum output frequency. 將頻率參考值提高到至少等於最小輸出頻率。 |
Motor Stops During Acceleration or When a Load is Connected (馬達在加速或連接負載時停止)
| 原因 (Cause) | 解決方案 (Possible Solution) |
|---|---|
| The load is too heavy. 負載過重。 • The limit of motor response may be reached during rapid acceleration. This may be a result of improper stall prevention or automatic torque boost function adjustment. 在快速加速期間，馬達響應可能達到極限。這可能是由於失速防止或自動轉矩提升功能調整不當所致。 | Increase the acceleration time (C1-01) or reduce the motor load. Also, consider increasing the motor size and/or drive size. 增加加速時間 (C1-01) 或減少馬達負載。此外，可考慮增加馬達尺寸和/或變頻器尺寸。 |
Motor Rotates in One Direction Only (馬達僅單向轉動)
| 原因 (Cause) | 解決方案 (Possible Solutions) |
|---|---|
| “Reverse run prohibited" is selected. If b1-04 (Reverse Prohibit Operation) is set to 1 (reverse run prohibited), the drive will not accept a reverse run command. 選取了「禁止反向運轉」。如果 b1-04（反向禁止運轉）設定為 1（禁止反向運轉），變頻器將不接受反向運轉指令。 | Set b1-04 = “0” to allow reverse run operation. 將 b1-04 設定為「0」以允許反向運轉。 |

Motor Operates at a Higher Speed than the Speed Command (馬達運轉速度高於速度指令)
| 原因 (Cause) | 解決方案 (Possible Solution) |
|---|---|
| PID is enabled. If the PID mode is enabled (b5-01 = 1 to 4), the drive output frequency will change to regulate the process variable to the target setpoint. The PID can command a speed up to maximum output frequency (E1-04). PID 已啟用。如果 PID 模式已啟用 (b5-01 = 1 至 4)，變頻器輸出頻率將會改變，以調節過程變數至目標設定點。PID 可指令速度最高達最大輸出頻率 (E1-04)。 | If PID operation is not target, disable PID by setting b5-01 = “0”. 如果 PID 運作並非目標，請將 b5-01 設定為「0」以停用 PID。 |
Poor Speed Control Accuracy Above Base Speed in Open Loop Vector Motor Control Method (開迴路向量馬達控制方法在基準速度以上時，速度控制精度不佳)
| Cause (原因) | Possible Solution (解決方案) |
|---|---|
| The maximum output voltage of the drive is determined by its input voltage. Vector control uses voltage to control the currents within the motor. If the vector control voltage reference value exceeds the drive output voltage capability, the speed control accuracy will decrease because the motor currents cannot be properly controlled. 變頻器的最大輸出電壓取決於其輸入電壓。向量控制使用電壓來控制馬達內的電流。如果向量控制的電壓參考值超過變頻器的輸出電壓能力，速度控制精度將會下降，因為馬達電流無法被適當控制。 | Use a motor with a lower rated voltage compared to the input voltage. 使用額定電壓低於輸入電壓的馬達。 |

Ground Fault Interrupter Activates When Drive is Running (變頻器運轉時接地故障斷路器跳脫)
| Cause (原因) | Possible Solutions (解決方案) |
|---|---|
| The output of the drive is a series of high frequency pulses (PWM), so there is a certain amount of leakage current. This may cause the ground fault interrupter to operate and cut off the drive input power. 變頻器的輸出是一系列高頻脈衝 (PWM)，因此會產生一定量的洩漏電流。這可能會導致接地故障斷路器跳脫並切斷變頻器的輸入電源。 | • Change to a ground fault interrupter with a higher leakage current detection level (such as a sensitivity current of 200 mA or greater per Unit, with an operating time of 0.1 s or more), or one that incorporates high-frequency corrective actions. 更換為具有更高洩漏電流偵測水平的接地故障斷路器（例如每台靈敏電流為 200 mA 或更高，運作時間為 0.1 秒或更長），或具備高頻修正功能的斷路器。 • Change the Carrier Frequency Selection (C6-02) to lower the carrier frequency. 更改載波頻率選擇 (C6-02) 以降低載波頻率。 Note: Leakage current increases in proportion to cable length. 注意：洩漏電流與電纜長度成正比增加。 |
