Troubleshooting
146
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.
