Cause
Mains voltage is too high
Braking operation
Earth leakage at motor end
All parameter sets are defective
Parameter set 1 is defective
Parameter set 2 is defective
Parameter set 3 is defective
Parameter set 4 is defective

Remedy
Check supply voltage
l
Increase deceleration times
l For operation with an external
brake resistor:
– Check dimensioning,
connection and supply cable of
the brake resistor
– Increase deceleration times
Check motor supply cable and motor
for earth fault (disconnect motor
from the inverter)
Before enabling the controller, repeat
the data transfer or load the Lenze
setting
Contact Lenze
Before enabling the controller, repeat
the data transfer or load the Lenze
setting.
Dependent on the error message
Close the circuit at the analog input
