Cause
Motor is not connected
l
Failure of one/several motor phases
l Motor current is too low
Mains voltage is too low
Voltage in DC−bus connection is too
low
400 V controller is connected to 240 V
mains
Short circuit
Capacitive charging current of the
motor cable is too high
A motor phase has earth contact
Capacitive charging current of the
motor cable is too high
Set acceleration time is too short
(C0012)
Defective motor cable
Interturn fault in the motor
Set deceleration time is too short
(C0013)
Frequent and too long overload periods Check drive dimensioning
Motor is thermally overloaded by e.g.
l impermissible continuous current
l
frequent or too long acceleration
processes
Ambient temperature is too high
Heatsink is very dirty
Impermissible high currents or
frequent and too long acceleration
processes
Motor too hot due to impermissible
high currents or frequent and too long
acceleration processes
No PTC connected
Controller is too hot inside
l
Remedy
Contact Lenze
Connect motor
l
Check motor supply cables
l Check V boost,
min
l
Connect motor with a corresponding
power or adapt motor with C0599
Check mains voltage
Check power supply module
Connect controller to correct mains voltage
l
Search for cause of short circuit; check
motor cable
l
Check brake resistor and cable to brake
resistor
Use shorter/low−capacitance motor cable
Check motor; check motor cable
Use shorter/low−capacitance motor cable
Deactivate earth−fault detection for test
purposes
l
Increase acceleration time
l
Check drive dimensioning
Check wiring
Check motor
l Increase deceleration time
l
Check dimensioning of the external brake
resistor
l Check drive dimensioning
l
Check setting of C0120
Allow controller to cool and provide for
better ventilation
Clean heatsink
l Check drive dimensioning
l Check load, replace rough−running,
defective bearings, if necessary
Check drive dimensioning
Connect PTC or switch off monitoring
l
Reduce controller load
l
Improve cooling
l Check fan in the controller
