Cause
Fan is defective
Fan is not connected
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)
l
Remedy
Replace fan
Connect fan
Check wiring
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
