To Next PageTo Next PageWhy is my Lenze 8210 HVAC 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 causes overload controller during deceleration in Lenze 8210 HVAC DC Drives?
An overload of the controller during deceleration is often due to a deceleration time (C013) that is too short. Increase the deceleration time and check the selection of the brake resistor or connect the brake chopper.
What does I x t overload mean in Lenze 8210 HVAC?
I x t overload can be caused by frequent and too long acceleration processes with overcurrent. In this case, check drive dimensioning.
What causes overload motor in Lenze 8210 HVAC DC Drives?
The motor can be overloaded if it's thermally overloaded, perhaps due to an impermissible continuous current. Check the drive selection. Frequent or overly long acceleration processes can also cause this; check the setting under C120.
What causes PTC monitoring issues in Lenze 8210 HVAC DC Drives?
PTC monitoring issues can arise if the motor is too hot due to excessive current or frequent and overly long acceleration. Check drive dimensioning. Also, the PTC might not be connected; connect the PTC or switch off monitoring (C0585=3).
What does overtemperature unit mean for Lenze DC Drives?
An overtemperature unit indicates that the inside of the unit is too hot. Reduce the controller load, improve cooling, and check the fan in the controller.
What causes faulty auto-TRIP reset in Lenze 8210 HVAC?
Faulty auto-TRIP reset is caused by more than 8 fault messages in 10 minutes. The solution depends on the fault message.
What to do if mains voltage is too high in Lenze 8210 HVAC 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 grounded motor phase in Lenze 8210 HVAC?
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.
What causes short circuit in Lenze 8210 HVAC DC Drives?
A short circuit can be caused by a short circuit itself. Find out the cause of the short circuit and check the cable. Also, excessive capacitive charging current of the motor cable can lead to a short circuit; use a motor cable which is shorter or of lower capacitance.
