not sensed. has tripped.
EEPROM Parameter save fault
checksum • faulty operation

SOLUTION
Decrease the motor load.
If no motor overload exists,
check the temperature model
parameters.
Attempt to reset.
Check value of counters.
Reset the fault and restart.
Should the fault re-occur, con-
tact Eaton.
Cancel prevention of start-up.
Check motor cooling and
loading Check thermistor con-
nection.
Check loading. Check motor
size.
Change control unit.
Reset

record!

Note: No fault time data
record!
Contact Eaton.
Check loading. Check motor
size.
Set the deceleration time lon-
ger. Use external brake resis-
tor.
Check encoder channel con-
nections.
Reset.
Note: No Fault Time Data
Record is made.

CORRECTIVE ACTION
Decrease the motor load.
If no motor overload exists, check the
temperature model parameters.
Check main Circuit breaker for trip.
Increase Current % imbalance in
VFD CONF (PIC III)/CFGUMVFD
(PIC 6) screen.
Reset the fault and restart.
Should the fault re-occur, contact
Eaton.
If thermistor input of the option board
is not in use, it must be short cir-
cuited.
Check VFD_CONF/CFGUMVFD
(PIC 6) screen.
See Eaton manual for location of con-
trol unit.
Press ICVC reset key.
Check option board.
Check option board.
Check VFD_CONF (PIC III)/CFGUM-
VFD (PIC 6) parameters.
Check VFD_CONF (PIC III)/CFGUM-
VFD (PIC 6) parameters.
Check the encoder board.
Press the reset key.
Note: Application parameter values
restored to default.
