Error Cause Remedy (1)
E1...E3 assigned with the same digital
Either just “UP” or “DOWN” used
Digital input “TRIP set” is active
Remote keypad disconnected
Short-circuit
Excessive capacitive charging current of the
motor cable
Acceleration time (C12) too short
Defective motor cable
Internal fault in motor
Frequent and long overload
Grounded motor phase
Excessive capacitive charging current of the
motor cable
Motor is thermally overloaded, for instance,
because of:
• impermissable continuous current
• frequent or too long acceleration processes
Controller too hot inside
Mains voltage too high
Earth leakage on the motor side
Excessively short deceleration time or motor
in generator mode
More than 8 errors in 10 minutes
• Use EPM providing valid data
• Load Lenze setting
Power down and replace EPM
Every digital signal can only be used once
Assign the missing digital signal to a second terminal
Remove external error
Check remote keypad connections
Find reason for short-circuit; check motor cable
Use shorter motor cables with lower charging
current
• Increase acceleration time
• Check drive selection
Check wiring
Check motor
Check drive selection
Check motor/motor cable
Use shorter motor cables with lower charging
current
• Check drive selection
• Check setting of c20
• Reduce controller load
• Improve cooling
Check mains voltage
Check motor/motor cable (separate motor from
controller)
Increase deceleration time or use dynamic braking
option
Depends on the error
dF dF dF dF dF Dynamic braking fault Dynamic braking resistors are overheating Increase deceleration time
