Single phase fault
(1) The drive can only be restarted if the error message has been reset; see c70
22
Digital input "TRIP set" is active
Serial timer has timed out
Serial communication failure
Remote keypad disconnected
Attempt was made to perform motor
calibration before setting C86...C91
Short-circuit
Excessive capacitive charging
current of the motor cable
Acceleration time (C12, c01) too short
Defective motor cable
Internal fault in motor
Frequent and long overload
Grounded motor phase
Excessive capacitive charging
current of the motor cable
t Motor is thermally overloaded, due to:
• impermissable continuous current
• frequent or too long acceleration
processes
Open-circuit on controller output when in
vector mode (C14 = 4, 5)
Controller too hot inside
Mains voltage too high
Excessively short deceleration time or
motor in generator mode
Earth leakage on the motor side
Controller was unable to synchronize with
motor during restart attempt
More than 8 errors in 10 minutes
4-20 mA signal (terminal 8I) is below 2
mA (C34 = 5)
A mains phase has been lost
Cause
Remove external error
Please contact Lenze
Check serial link connections
Please contact Lenze
Check remote keypad connections
Must set C86...C91 before performing
motor calibration (see c48)
Find reason for short-circuit; check
motor cable
Use shorter motor cables with lower
charging current
• Increase acceleration time
• Check controller selection
Check wiring
Check motor
Check controller selection
Check motor/motor cable
Use shorter motor cables with lower
charging current
• Check controller selection
• Check setting of c20
• Motor must be connected in vector
• Check motor/motor cable
• Reduce controller load
• Improve cooling
Check mains voltage
Increase deceleration time or use
dynamic braking option
Check motor/motor cable
(separate motor from controller)
Check motor/load
Depends on the error
Check signal/signal wire
Check mains voltage
