What to do if Lenze DC Drives controller does not transmit telegrams?
If the Lenze DC Drives controller does not transmit telegrams, first check if the yellow LED TxD is blinking. If it's not, verify the LECOM baud rate (C0125) of both nodes and adjust them to be the same if needed. Avoid using device addresses 00, 10, ..., 90. If the yellow LED TxD is blinking, then check the wiring to the host.
What to do if Lenze DC Drives controller does not receive any telegrams?
If the Lenze DC Drives controller does not receive telegrams, and the yellow LED RxD is not blinking, check the wiring to the host. Also, ensure that the host is transmitting telegrams using the correct interface. You can test this by having the host transmit telegrams cyclically, for example, with GDC in online operation.
Why Lenze DC Drives motor does not rotate?
If the motor does not rotate when using Lenze DC Drives, it could be due to several reasons. Here are some things to check: * The DC-bus voltage may be too low, so check the mains voltage. * The controller may be inhibited, so remove the controller inhibit. * The quick stop may be active, so remove the quick stop. * The setpoint may be 0, so select a setpoint. * An active fault may be present, so eliminate the fault.
How to fix Lenze DC Drives motor that does not rotate smoothly?
If your Lenze DC Drives motor isn't rotating smoothly, start by checking the motor cable for any defects. Also, make sure that the maximum current settings (C0022, C0023) are appropriately adapted to the application.
How to troubleshoot no communication with Lenze DC Drives controller?
If the Lenze DC Drives controller is switched off, supply the controller with voltage. If the communication module has no voltage, check the connection with the controller.
Why Lenze DC Drives controller transmits positive acknowledgement but does not execute write request?
If the Lenze DC Drives controller transmits a positive acknowledgement (ACK response) but does not execute the write request, it might be operating with a different parameter set. Try changing over to the correct parameter set.
What to do if Lenze DC Drives motor does not rotate because automatic start is inhibited?
If the motor does not rotate when using Lenze DC Drives and the automatic start is inhibited, correct the start condition (C0142). Apply a LOW-HIGH edge at X3/28 if necessary.
What to do if Lenze DC Drives motor does not rotate because DC injection brake is active?
If the Lenze DC Drives motor does not rotate and the DC injection brake (DCB) is active, deactivate the DC injection brake.
What to do if Lenze DC Drives motor does not rotate because mechanical motor brake is not released?
If the Lenze DC Drives motor does not rotate and the mechanical motor brake is not released, manually or electrically release the mechanical motor brake.
What to do if Lenze DC Drives motor does not rotate because JOG frequency is 0?
If the Lenze DC Drives motor does not rotate and the JOG setpoint is activated but the JOG frequency is 0, select a JOG setpoint (C0037 ... C0039).
