Fault Cause Remedy
F001
H001
Motor: overcurrent Motor overloaded by impermissible
continuous current Check drive dimensioning.
Rated motor current set incorrectly Check setting of C0120.
F002
Control system: internal temperature
too high Ambient temperature too high Reduce ambient temperature.
F003
H003
Control system: mains voltage too
low Failure of one or several mains phases l Check supply feeder/collector.
l
Check fuses.
Mains voltage too low Check mains voltage.
F004
Control system: mains voltage too
high Mains voltage too high l Check supply feeder/collector.
l Check mains voltage.
l
Check setting of C0016.
F005
Control system: fault in the output
stage Fault in wiring on the motor side Correct motor wiring.
Motor defective Replace motor.
Control system defective Replace control system.
F006
H006
Motor: high−resistance thermistor Motor too warm from impermissibly
high currents Check drive dimensioning.
No PTC or thermal contact connected Connect PTC or thermal contact or
switch off monitoring with C0120 = 0.
F008
Frequency inverter: parameter error Inconsistency within the parameters
of the frequency inverter, e. g.
because the external data memory
has been removed during a voltage
was applied l Load Lenze setting
l
Transfer parameter data again.
Thereby always wait until the
PAr
message goes out. Only then
switch off the voltage.
F011
H011
Motor: phase U failed Motor phase U failed Check motor and motor wiring.
F012
H012
Motor: phase V failed Motor phase V failed Check motor and motor wiring.
F013
H013
Motor: phase W failed Motor phase W failed Check motor and motor wiring.
F014
Frequency inverter: overload of
internal brake resistor Overload by operation in generator
mode l Let control system cool down.
l
Reduce number of brake
applications.
l Reduce loading of vehicle.
F018
Frequency inverter: initialisation error Internal communication error Switch off mains voltage and then
switch it on again. If the error occurs
again, replace control system
F019
Frequency inverter: not ready for
operation Internal communication error Switch off mains voltage and then
switch it on again. If the error occurs
again, replace control system.
H020
Control: 24 V voltage supply too low
l
Failure of one or several mains
phases
l
Mains voltage too low
l Overload of the 24 V voltage
supply on the control connections
for encoders, sensors, etc.
l
Check supply feeder/collector
l
Check fuses
l
Check mains voltage
l Check encoders, sensors connected
and their cabling
