What to do if DC-injection brake is active in Lenze Tmd?
If the DC-injection brake is active in Lenze DC Drives, it was activated either via digital input or automatically. Deactivate the DC-injection brake by ensuring the digital input is LOW. If activated automatically, it will deactivate after the holding time c06 has expired.
How to fix an earth fault in Lenze Tmd DC Drives?
To fix an earth fault in Lenze DC Drives, check the motor and motor cable for a grounded motor phase. Also, excessive capacitive charging current of the motor cable can cause this, so use shorter motor cables with lower charging current.
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 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.
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 motor calibration is in process on Lenze Tmd DC Drives?
If motor calibration is in process on Lenze DC Drives, and c48 = 1 and terminal 28 = HIGH, only perform the motor calibration when C14 = 4...7.
Why buttons on Lenze Tmd DC Drives are disabled when remote keypad is active?
When the remote keypad is active on Lenze DC Drives, the buttons on the front of the controller are disabled. This is the designed behavior.
What to do if Lenze DC Drives lose 4-20 mA reference?
If Lenze DC Drives lose the 4-20 mA reference signal (terminal 8I) and it's below 2 mA (C34 = 5), check the signal and signal wire for any issues.
What causes automatic start inhibited on Lenze DC Drives?
If automatic start is inhibited on Lenze DC Drives, and c42 = 0, 2, apply a LOW-HIGH signal change at terminal 28.
How to resolve drive identification fault in Lenze Tmd DC Drives?
To resolve a drive identification fault in Lenze DC Drives, ensure that you set C86...C91 before performing motor calibration. Refer to c48 for more information.
