7.2 Fault-finding
The table below should be regarded as a “First-aid” box. Depending on the conditions in
your installation, there may be a wide variety of reasons for the fault. In multi-axis sys-
tems there may be further hidden causes of a fault. Our customer support can give you
further assistance with problems.
Fault possible causes Measures to remove the fault
HMI message:
communication
fault
— wrong cable used
— cable plugged into wrong posi-
tion in
servo amplifier or PC
— wrong PC interface selected
— use null-modem cable
— plug cable into the correct so-
ckets on the servo amplifier
and PC
— select correct interface
F01 message:
heat sink
temperature — permissible heat sink tempera-
ture exceeded
— improve ventilation
F02 message:
overvoltage
— regen power is insufficient. re-
gen power limit was reached
and the regen resistor was
switched off. This causes ex-
cessive voltage in the DC Bus
link circuit.
— supply voltage too high
— shorten the braking time RAMP
or use an external regen resis-
tor with a higher power rating
and adjust the regen power pa-
rameter
— use mains transformer
F04 message:
feedback unit
— feedback connector not inser-
ted
— feedback cable is damaged
— check connector
— check cable
F05 message:
undervoltage
— supply voltage not present or
too low when servo amplifier is
enabled
— only enable the servo amplifier
when the mains supply voltage
has been switched on delay >
500 ms
F06 message:
motor tempera-
ture
— motor thermostat has been ac-
tivated
— feedback connector is loose or
break in feedback cable
— wait until motor has cooled
down, then check why it beca-
me so hot
— tighten connector or new feed-
back cable
F07 message:
aux. voltage
— the aux. voltage produced by
the servo amplifier is incorrect
— return the servo amplifier to the
manufacturer for repair
F08 message:
motor runs
away
(overspeed) — motor phases swapped
— feedback set up incorrectly
— faulty connection to feedback
unit
— correct motor phase sequence
— set up correct offset angle
— check connector
F11 message:
brake
— short-circuit in the supply cable
for the motor-holding brake
— motor-holding brake is faulty
— fault in brake cable
— no brake connected, although
the brake parameter is set to
"WITH"
— remove short-circuit
— replace motor
— check shielding of brake cable
— brake parameter set to "WIT-
HOUT"
F13 message:
int. temperature — permissible internal temperatu-
re exceeded
— improve ventilation
