What to do if Lenze 9300 displays a short-circuit error?
If your Lenze Controller shows a 'Short-circuit' error, it indicates an electrical short. You should identify and fix the cause of the short-circuit and inspect the cable. It could also be due to excessive capacitive charging current of the motor cable. In this case, use a motor cable that is shorter or has lower capacitance.
What causes an earth fault in Lenze 9300?
If your Lenze Controller displays an 'Earth fault' error, it means one of the motor phases has contact with the earth or there's excessive capacitive charging current in the motor cable. Check the motor and supply module. Also, consider using a shorter motor cable or one with lower capacitance.
What does motor phase failure mean on Lenze 9300?
If your Lenze Controller shows a 'Motor phase failure', it indicates that a current-carrying motor phase has failed, or the current limit is set too high. Check the motor and the supply module. Set a lower current limit value under C0599.
Why does my Lenze 9300 Controller show a communication error?
A communication error on your Lenze Controller may arise from interference during the transmission of control commands via the automation interface X1, or faulty data received by CAN_IN objects. Ensure the automation module is firmly plugged in and bolted down if necessary. Also, check the cable at X4, inspect the transmitter, and increase the monitoring time under C0357/1, C0357/2, or C0357/3 if needed.
How to troubleshoot high heat sink temperature on Lenze 9300 Controller?
If the heat sink temperature of your Lenze Controller is higher than the set value, it could be due to a high ambient temperature (Tamb > 40 °C or 50 °C), a dirty heat sink, or an incorrect mounting position. Allow the controller to cool and improve ventilation. Check the ambient temperature in the control cabinet. Clean the heat sink and change the mounting position if necessary.
How to resolve BUS-OFF state on Lenze 9300 Controller?
If your Lenze Controller enters a BUS-OFF state, it indicates that the controller has received too many incorrect telegrams via the system bus X4 and has disconnected from the bus. Check the wiring, bus termination (if any), screen contact of the cables, PE connection, and bus load. Reduce the baud rate, considering the cable length.
What causes overvoltage on Lenze 9300 Controller?
If your Lenze Controller displays an 'Overvoltage' error, it's likely due to excessive brake energy, causing the DC bus voltage to exceed the value set under C0173. To resolve this, use a brake module or an energy recovery module.
What to do for a data error on Lenze 9300 Controller?
If your Lenze Controller shows a 'Data error', it could be due to an attempt to accept faulty data or an incorrect checksum of the transferred data. Initiate a new data transfer and check the data.
What does I x t overload mean on Lenze 9300 Controller?
If your Lenze Controller displays 'I x t overload', it is likely due to frequent and prolonged acceleration with overcurrent or continuous overload with Imotor exceeding 1.05 x Irx. Check the drive dimensioning.
Why does my Lenze 9300 Controller show PTC overheating at terminals T1, T2?
If your Lenze Controller indicates that the 'PTC at terminals T1, T2 indicates motor overheating,' it means the motor is too hot due to excessive current or frequent and prolonged acceleration, or the terminals T1, T2 are not assigned. Check the drive dimensioning. Connect the PTC or thermostat, or switch off monitoring (C0585=3).
