What causes overload during deceleration in Lenze DC Drives?
If the Lenze DC Drives controller overloads during deceleration, the deceleration time might be too short. Increase the deceleration time. Also check the selection of the brake resistor or connect the brake chopper.
How to fix Lenze 8201 DC Drives motor that does not rotate smoothly?
If your Lenze DC Drives motor isn't rotating smoothly, it could be due to a defective motor cable, so replace it. The maximum current settings C022 and C023 might be too low, so adjust them. Also, the motor could be underexcited or overexcited, so check the parameter settings.
Why is current consumption of Lenze DC Drives motor too high?
If the current consumption of your Lenze DC Drives motor is too high, the setting of C016 might be too high, so lower it. Alternatively, the setting of C015 might be too low, so increase it. Also, ensure that C088 and C091 are adapted to the motor data.
Why is the heat sink temperature too high in my Lenze 8201?
If the heat sink temperature is higher than the set value in your Lenze DC Drives controller, it could be due to several reasons. The ambient temperature might be too high (T > +40 C or +50 C amb). Allow the controller to cool and ensure proper ventilation. The heat sink might be very dirty, so clean it. The mounting position could be incorrect, so change it.
What to do for external fault (TRIP-Set) in Lenze DC Drives?
If you're experiencing an external fault (TRIP-Set) with your Lenze DC Drives, a digital input assigned to the TRIP-Set function might have been activated. Check external encoder.
How to troubleshoot short circuit in Lenze 8201?
If you're experiencing a short circuit with your Lenze DC Drives, first find out the cause of the short circuit and check the cable. It could also be due to excessive capacitive charging current of the motor cable. In that case, use a motor cable which is shorter or of lower capacitance.
What to do if Lenze 8201 motor does not rotate?
If your Lenze DC Drives motor isn't rotating, several factors could be at play. The DC-bus voltage might be too low, so you should check the mains voltage. The controller might be inhibited; in that case, check the display of the operating module for OFF, STOP, or AS_LC. Also, the setpoint could be zero, requiring you to modify it. DC braking or the Quick-stop function might be active, so deactivate them. If a JOG setpoint is activated with a JOG frequency of 0, set the JOG frequency to a non-zero value. Also, check the mechanical motor brake to ensure it is released.
What to do if Lenze Inverter shows faulty parameter transfer?
If there's a faulty parameter transfer via the operating module on your Lenze Inverter because PAR1 and PAR2 are defective, repeat the data transfer or load the factory setting before enabling the controller.
What does EEr external fault mean on Lenze Inverter?
If your Lenze Inverter displays an EE|External fault (TRIP-Set) error, it means a digital input assigned to the TRIP-Set function has been activated. Check the external encoder.
What does LU undervoltage mean on Lenze Inverter?
If your Lenze Inverter displays an LU (Undervoltage) error, it means the DC-bus voltage is too low. Check the mains voltage and the supply module.
