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 causes faulty auto-TRIP reset in Lenze 8204 DC Drives?
If you have a faulty auto-TRIP reset on your Lenze DC Drives, it could be due to more than 8 fault messages in 10 minutes. The solution depends on the specific fault message.
Why Lenze Inverter motor does not rotate?
If the Lenze Inverter motor isn't rotating, it could be due to several reasons: * The DC-bus voltage might be too low, in this case check the mains voltage. * The controller might be inhibited, so check the operating module. * The setpoint might be zero, so set a proper setpoint. * DC braking or the quick-stop function could be active, so disable them. * If a JOG setpoint is activated but the JOG frequency is zero, set the JOG frequency. * A fault might be indicated (refer to chapter 8.3 for fault details). * The mechanical motor brake might not be released, so release it.
What to do if Lenze Inverter shows OOV overvoltage error?
If your Lenze Inverter displays an OOV (Overvoltage) error, it could be due to: * Mains voltage being too high, check the voltage supply. * Feedback or braking operation issues. Try increasing deceleration times. If using brake choppers, check the selection and connection of the brake resistor and increase the deceleration times. * Earth leakage on the motor side. Inspect the motor cable and motor for earth faults, disconnecting the motor from the inverter to do so.
How to fix Lenze Inverter heat sink temperature too high?
If the heat sink temperature of your Lenze Inverter is too high, consider the following: * The ambient temperature might be too high (Tamb > +40 C or +50 C). Allow the controller to cool and ensure proper ventilation. Also, check the ambient temperature in the control cabinet. * The heat sink might be dirty, so clean it. * The mounting position might be incorrect, so change it.
What causes OC1 short circuit in Lenze Inverter?
If your Lenze Inverter displays an OC1 (Short circuit) error, it could be due to: * A short circuit. Find out the cause of the short circuit and check the cable. * Excessive capacitive charging current of the motor cable. Use a motor cable that is shorter or of lower capacitance.
How to fix Lenze 8204 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.
What causes overvoltage in Lenze 8204 DC Drives?
If your Lenze DC Drives unit is experiencing overvoltage, it could be due to mains overvoltage lasting longer than 5 seconds. You should check the mains voltage.
What to do if Lenze 8204 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 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.
