Why is the current consumption of my Lenze EVF8212-EV020 motor too high?
High current consumption in the motor can be attributed to a few settings. The setting of C016 might be too high, or the setting of C015 might be too low. Additionally, C088 and C091 might not be adapted to the motor data.
What causes grounded motor phase in Lenze EVF8212-EV020 DC Drives?
A grounded motor phase can be caused by a grounded motor phase. Check the motor and cable. Also, excessive capacitive charging current of the motor cable can lead to a grounded motor phase; use a motor cable which is shorter or of lower capacitance.
Why is my Lenze EVF8212-EV020 DC Drives motor not rotating smoothly?
If the motor isn't rotating smoothly, it could be due to a defective motor cable. The maximum current C022 and C023 might also be set too low. Another possibility is that the motor is underexcited or overexcited; check the parameter setting.
What to do if mains voltage is too high in Lenze DC Drives?
If the mains voltage is too high, check the voltage supply. It could also be due to feedback operation during braking. Increase deceleration times. For operation with brake choppers, check the selection and connection of the brake resistor and increase the deceleration times. Another cause may be Earth leakage on the motor side, check motor cable and motor for earth fault (disconnect motor from inverter).
What causes faulty parameter transfer via the operating module in Lenze EVF8212-EV020 DC Drives?
If PAR1 and PAR2 are defective, it can cause a faulty parameter transfer. It is absolutely necessary to repeat the data transfer or load the factory setting before enabling the controller.
What causes faulty auto-TRIP reset in Lenze EVF8212-EV020?
Faulty auto-TRIP reset is caused by more than 8 fault messages in 10 minutes. The solution depends on the fault message.
