11.4 Removing faults
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.
Error messages of the PMCprimo Drive2 are described detailed in the PMCprimo programming
manual. Our applications department can give you further assistance with problems.
Fault possible causes Measures to remove the cause of the
fault
message:
communication
fault
— wrong cable used
— cable plugged into wrong position in
PMCprimo Drive2
or PC
— wrong COM port selected
— use null-modem cable
— plug cable into the correct sockets on
the PMCprimo Drive2 and PC
— select correct interface
message:
undervoltage
— supply voltage not present or too low
when PMCprimo Drive2
is enabled
— only enable the PMCprimo Drive2
when the mains supply voltage has
been switched on delay > 500 ms
message:
overvoltage
— regen power is insufficient. regen power
limit was reached and the regen resistor
was switched off. This causes excessive
voltage in the DC-link circuit.
— supply voltage too high
— shorten the braking time RAMP or
shorten the braking time RAMP or
with a higher power rating and adjust
the regen power parameter
— use mains transformer
message:
mains BTB/RTO
— enable was applied, although the supply
voltage was not present.
— at least 2 supply phases are missing
— only enable the servo amplifier when
the mains supply voltage has been
switched on
— check electrical supply
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 "WITHOUT"“
message:
output stage fault
— motor cable has short-circuit/ground short
— motor has short-circuit / ground short
— output module is overheated
— output stage is faulty
— short-circuit / short to ground in the
external regen resistor
— replace cable
— replace motor
— improve ventilation
— return the servo amplifier to the
manufacturer for repair
— remove short-circuit / ground short
message:
heat sink
temperature
— permissible heat sink temperature
exceeded
— improve ventilation
message:
aux. voltage
— the aux. voltage produced by the servo
amplifier is incorrect
— return the servo amplifier to the
manufacturer for repair
