What to do if Lenze Tmd lose motor phase?
If there is a loss of motor phase in Lenze DC Drives, and the controller is in vector mode (C14 = 4, 5), ensure the motor is connected correctly in vector mode. Also, check the motor and motor cable for any open-circuits.
What causes dynamic braking fault on Lenze DC Drives?
A dynamic braking fault in Lenze DC Drives is caused by the dynamic braking resistors overheating. To resolve this, increase the deceleration time.
How to fix EPM error on Lenze DC Drives?
To fix an EPM error on Lenze DC Drives, power down the drive and replace the EPM, as the error indicates that the EPM is either missing or defective.
What to do if Lenze DC Drives controller is overtemperature?
If the Lenze DC Drives controller is too hot inside, reduce the controller load and improve cooling to resolve the overtemperature issue.
What causes motor overload on Lenze Tmd?
Motor overload (I2t overload) in Lenze DC Drives is typically caused by the motor being thermally overloaded due to impermissible continuous current or frequent/long acceleration processes. Check the controller selection and the setting of c20 to resolve this issue.
What to do if Lenze DC Drives show a short-circuit or overload?
If your Lenze DC Drive indicates a short-circuit, first find the reason for the short-circuit and check the motor cable. If there is excessive capacitive charging current of the motor cable, use shorter motor cables with lower charging current. If the acceleration time is too short, increase it and check the controller selection. Also, check the wiring and the motor for defects. Finally, if there's frequent and long overload, check the controller selection.
