Why is my Lenze TML Media Converter inhibited (outputs U, V, W inhibited)?
If the outputs U, V, W are inhibited on your Lenze Media Converter, it might be because the controller is set up for a remote keypad. Try starting the controller via the remote keypad.
Why is Lenze Media Converter showing controller overtemperature?
If your Lenze Media Converter displays a controller overtemperature warning, it means the controller is too hot inside. Reduce the controller load or improve cooling.
What causes motor overload (I2t overload) in Lenze Media Converter?
Motor overload (I2t overload) in your Lenze Media Converter happens when the motor is thermally overloaded due to impermissible continuous current or frequent/long acceleration processes. Check the controller selection and the setting of c20.
Why is there undervoltage on DC bus in Lenze Media Converter?
Undervoltage on the DC bus of your Lenze Media Converter typically occurs because the mains voltage is too low. Check the mains voltage.
What to do if Lenze Media Converter shows earth fault?
If your Lenze Media Converter indicates an earth fault, check the motor and motor cable for a grounded motor phase or excessive capacitive charging current. Consider using shorter motor cables with lower charging current.
What causes Lenze Media Converter to stop (outputs U, V, W inhibited)?
The Lenze Media Converter may stop with inhibited outputs U, V, W due to a LOW signal at terminal 28. To resolve this, set terminal 28 to HIGH.
What to do if there is overvoltage on DC bus of Lenze Media Converter?
If you are experiencing overvoltage on the DC bus of your Lenze Media Converter, check the mains voltage, increase deceleration time or use dynamic braking option, or check the motor/motor cable for earth leakage (separate motor from controller).
