* = 2...6 Module number if parallel power units (size 300–3000 A)
** = If no size is mentioned in this column, the information is valid for all sizes.
OPTION
If an Option specific trip occurs
Check the description of the specific option
Desat
Failure in output stage,
- desaturation of IGBTs
- Hard short circuit between phases or
phase to earth
- Earth fault
- For size B - D also the Brake IGBT
-
Check on bad motor cable connections
-
Check on bad earth cable connections
-
Check on water and moisture in the
motor housing and cable connections
-
Check that the rating plate data of the motor is
correctly entered.
-
Check the brake resistor, brake IGBT and wiring.
-
For size G and up, check the cables from the
PEBBs to the motor, that all are in correct order in
parallell connection

DC link error
DC link voltage ripple exceeds maximum
level
-
Make sure all three phases are properly connected
and that the terminal screws are tightened.
-
Check that the mains supply voltage is within the
limits of the AC drive.
-
Try to use other mains supply lines if dip is caused
by other machinery.
Power Fault
One of the 10 PF (Power Fault) trips below
has occured, but could not be determined.
-
Check the PF errors and try to determine the
cause. The trip history can be helpful.
PF Fan Err *
Error in fan module
-
Check for clogged air inlet filters in panel door and
blocking material in fan module.
>=90A
PF HCB Err*
Error in controlled rectifier module (HCB)
-
Check mains supply voltage
>=
60
A
PF Curr Err *
Error in current balancing:
- between different modules.
- between two phases within one module.
-
Check motor.
-
Check fuses and line connections
-
Check the individual motor current leads with an
clamp on amp meter.
>=
300
A
PF Overvolt *
Error in voltage balancing, overvoltage
detected in one of the power modules
(PEBB)
-
Check motor.
-
Check fuses and line connections.
>=
300
A
PF Comm Err *
Internal communication error
Contact service
PF Int Temp *
Internal temperature too high
Check internal fans
PF Temp Err *
Malfunction in temperature sensor
Contact service
PF DC Err *
DC-link error and mains supply fault
-
Check mains supply voltage
-
Check fuses and line connections.
>=
60
A
PF Sup Err *
Mains supply fault
-
Check mains supply voltage
-
Check fuses and line connections.
Brake
Brake tripped on brake fault (not released)
or Brake not engaged during stop.
-
Check Brake acknowledge signal wiring to selected
digital input.
-
Check programming of digital input DigIn 1-8
[520]
-
Check circuit breaker feeding mechanical brake
circuit.
-
Check mechanical brake if acknowledge signal is
wired from brake limit switch.
-
Check brake contactor.
-
Check settings [33C], [33D], [33E], [33F].
