Cause
Controller is too hot inside
Motor too hot due to impermissible
high currents or frequent and too long
acceleration processes
No PTC connected
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
EEPROM is defective
Data flow from keypad or PC
interrupted, e.g. keypad has been
removed during data transmission

Remedy
l
Reduce controller load
l
Improve cooling
l
Check fan in the controller
Check drive dimensioning
Connect PTC or switch off monitoring
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.
