Finding and removing faults

The table below should be regarded as a "First-aid" box. There may be a wide variety of
reasons for the fault, depending on the conditions in your installation.
In multi-axis systems there may be further hidden causes of a fault.
Our customer service can give you further assistance with problems.

Possible causes
— wrong cable used
— cable plugged into wrong position
on servo amplifier or PC
— wrong PC interface selected
— permissible heat sink tempe-
rature exceeded
— regen power is insufficient.
Regen power limit was reached
and the regen resistor was
switched off.
This causes excessive voltage
in the DC bus link circuit.
— supply voltage too high
— feedback connector not properly
inserted
— feedback cable is broken,
crushed, or otherwise damaged
— feedback unit is damaged or
wrongly configured
— supply voltage is not present, or
too low when the servo amplifier
is enabled
— motor thermostat has been
activated
— feedback connector is loose, or
a break in the feedback cable
— the aux. voltage produced by the
servo amplifier is incorrect
— motor phases swapped
— feedback device set up
incorrectly
— checksum error

Measures
— use null-modem cable
— plug cable into the correct
sockets on the servo amplifier
and PC
— select correct interface
— improve ventilation
— reduce the RAMP braking
time.
Use an external regen resistor
with a higher power rating and
adjust the regen power
parameter
— use a supply transformer
— check connectors
— check cables
— check feedback unit and
settings
— only ENABLE the servo
amplifier when the electrical
supply voltage has been
switched on delay > 500 msec
— wait till motor has cooled
down, then check why it
became so hot.
— screw connector up tight, or
use new feedback cable
— return the servo amplifier to
the manufacturer for repair
— correct motor phase sequence
— set up the correct offset angle
— save data to EEPROM again
to force a new calculation
