Name Description Possible Causes & Corrective Action
Setup Fault 10
[F30]
This fault is declared when a run is
issued and the Input L-L Volts (A4) is
set to 000.00 Check Parameters Settings:

Check Input L-L Volts (A4)

Verify setting of Input L-L Volts matches
measure AC Input to Drive
Setup Fault 11
[F31]
This fault is declared if ENCODER
SELECT (C1) = ENDAT ABSOLUTE
and the number of pulses entered in
ENCODER PULSES (A1) is greater
than 3125
Check Parameters Settings:

Verify the setting of ENCODER SELECT
(C1)

If an EnDat Absolute Encoder is used
and ENCODER SELECT (C1) is set to
ENDAT ABSOLUTE
– verify the value
placed in ENCODER PULSES (A1) is
between 500
– 3125
Setup Fault 12
[F32]
This fault is declared when one or
more parameter values are set outside
the acceptable limit when

the U9 Drive Mode is changed
from one to another

or the parameters were being
loaded from EE to RAM.
Check Parameters Settings:

Verify the setting of ALL parameters

Default the drive parameters to factory
defaults in U5 Restore Defaults
o
reload all the parameters
o
go through all the parameters and
set them manually to the correct
values
Short Circuit
[F52]
The integrated power module is
sensing an overcurrent or over
temperature condition Overcurrent Problem

Check for a possible short between the
motor windings.

Verify dynamic brake resistor size (could
be too small)
Overtemperature Problem

Reduce Ambient Temperature

Clean heat sink

Check for cooling fan failure
The drive may need to be replaced, if no
other problem found.
