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.

possible causes
— wrong cable used
— cable plugged into wrong position in
PMCprimo Drive2 or PC
— wrong COM port selected
— supply voltage not present or too low
when PMCprimo Drive2 is enabled
— 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
— enable was applied, although the supply
voltage was not present.
— at least 2 supply phases are missing
— 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"
— 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
— permissible heat sink temperature
exceeded
— the aux. voltage produced by the servo
amplifier is incorrect
11 Appendix
Measures to remove the cause of the
fault
— use null-modem cable
— plug cable into the correct sockets on
the PMCprimo Drive2 and PC
— select correct interface
— only enable the PMCprimo Drive2
when the mains supply voltage has
been switched on delay > 500 ms
— 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
— only enable the servo amplifier when
the mains supply voltage has been
switched on
— check electrical supply
— remove short-circuit
— replace motor
— check shielding of brake cable
— brake parameter set to "WITHOUT""
— replace cable
— replace motor
— improve ventilation
— return the servo amplifier to the
manufacturer for repair
— remove short-circuit / ground short
— improve ventilation
— return the servo amplifier to the
manufacturer for repair
