What to do if Lenze ESMD751X2SFA Inverter shows short-circuit or overload?
If the Lenze Inverter displays a short-circuit or overload error, this is likely due to a short-circuit condition. To resolve this, identify the cause of the short-circuit and inspect the motor cable.
Why Lenze Inverter displays undervoltage on DC bus?
If you're seeing an undervoltage error on the DC bus of your Lenze Inverter, the mains voltage may be too low. Verify that the mains voltage is within the acceptable range.
How to fix motor overload (I2t overload) on Lenze ESMD751X2SFA?
If the Lenze Inverter indicates a motor overload (I2t overload), the motor is likely overheating due to an impermissible continuous current or frequent/lengthy acceleration. Address this by checking the controller selection and the setting of c20.
What causes external error on Lenze ESMD751X2SFA?
If your Lenze Inverter is showing an external error, it means the digital input “TRIP set” is active. To resolve this, you should remove the external error.
How to deactivate DC-injection brake on Lenze Inverter?
The DC-injection brake may be active on your Lenze Inverter because it was activated via digital input or automatically. To deactivate it, ensure the digital input is LOW, or wait for it to deactivate automatically after the holding time c06 has expired.
What to do if Lenze ESMD751X2SFA Inverter shows EPM error?
If your Lenze Inverter displays an EPM error, the EPM is either missing or defective. Power down the Inverter and replace the EPM.
Why Lenze Inverter shows digital inputs not uniquely assigned?
If the Lenze Inverter indicates that digital inputs are not uniquely assigned, this means that E1...E3 are assigned with the same digital signals. Ensure that each digital signal is only used once.
Why automatic start inhibited on Lenze Inverter?
If automatic start is inhibited on your Lenze Inverter, it is because c42 = 0. Apply a LOW-HIGH signal change at terminal 28.
How to solve Lenze ESMD751X2SFA stop with inhibited outputs U, V, W?
If the Lenze Inverter has stopped and outputs U, V, and W are inhibited, this is due to a LOW signal at terminal 28. Set terminal 28 to HIGH.
