What does 'Current limit reached' mean on Lenze ESMD?
- JJennifer EllisSep 23, 2025
If your Lenze DC Drives display 'Current limit reached', it indicates a controllable overload. This will be managed automatically.
What does 'Current limit reached' mean on Lenze ESMD?
If your Lenze DC Drives display 'Current limit reached', it indicates a controllable overload. This will be managed automatically.
What to do if Lenze ESMD display 'Earth fault'?
If your Lenze DC Drives are displaying an 'Earth fault', this could be due to a grounded motor phase or excessive capacitive charging current in the motor cable. Check the motor and motor cable. If the issue persists, try using shorter motor cables to reduce the charging current.
What does it mean when my Lenze ESMD says 'Motor overload (I2t overload)'?
The 'Motor overload (I2t overload)' message on your Lenze DC Drives indicates the motor is thermally overloaded. This could be due to an impermissible continuous current or frequent/long acceleration processes. Check the drive selection and the setting of c20.
Why Lenze ESMD show 'Single phase fault'?
If your Lenze DC Drives are showing a 'Single phase fault', it usually means a mains phase has been lost. In this case, check the mains voltage supply.
How to resolve Lenze ESMD DC Drives 'Dynamic braking fault'?
A 'Dynamic braking fault' in Lenze DC Drives indicates that the dynamic braking resistors are overheating. To fix this, increase the deceleration time.
What does it mean if my Lenze ESMD DC Drives says 'DC-injection brake active'?
If your Lenze DC Drives indicate that the 'DC-injection brake' is active, this means it has been activated either via digital input or automatically. To deactivate it, set the digital input to HIGH, or wait for it to deactivate automatically after the holding time c06 has expired.
What does it mean if my Lenze ESMD DC Drives are in 'Stop' mode (outputs U, V, W inhibited)?
If your Lenze DC Drives are in 'Stop' mode with outputs U, V, W inhibited, it's likely due to a LOW signal at terminal 28. Set terminal 28 to HIGH to resolve this.
What does 'Remote keypad is active' mean for Lenze ESMD DC Drives?
If 'Remote keypad is active' on your Lenze DC Drives, it means the buttons on the front of the controller are disabled. This is normal operation when a remote keypad is in use.
What to do if Lenze ESMD is too hot inside (Controller overtemperature)?
If your Lenze DC Drives are overheating, it means the controller is too hot inside. You can resolve this by reducing the controller load or improving the cooling.
What causes 'Overvoltage on DC bus' in Lenze ESMD DC Drives?
An 'Overvoltage on DC bus' error in Lenze DC Drives can be due to several reasons: * Mains voltage being too high. Check the mains voltage. * An excessively short deceleration time or the motor operating in generator mode. Increase the deceleration time or consider using a dynamic braking option. * Earth leakage on the motor side. Inspect the motor and motor cable, separating the motor from the controller during the check.
