Why Lenze Inverter motor does not rotate smoothly?
If the Lenze Inverter motor isn't rotating smoothly: * The motor cable might be defective, so replace it. * The maximum current settings (C022 and C023) might be too low, so adjust them. * The motor might be underexcited or overexcited, so check the parameter setting.
How to reduce high current consumption of motor with Lenze Inverter?
If the motor's current consumption is too high when using a Lenze Inverter: * Reduce the setting of C016. * Increase the setting of C015. * Adapt C088 and C091 to the motor data.
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 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 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.
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.
