6.6 FAULT AND WARNING
CODES
The Supervisor constantly monitors drive
performance through the serial channel. The
following messages are specifically displayed by the
Supervisor in the event of problems.
Fault Possible Cause Solution
VSD Param Lim Fault Incorrect model, HP or Voltage selected in
Factory & VSD Setup
Make proper selections
VSD Com Error Communications lost with the VSD Check connections to the VSD.
Check VSD control power and check
for board faults.
VSD Emergency Stop
(VSD Code 51)
Emergency Stop is pressed
Break in Estop wiring
Clear the package emergency stop.
Check Estop wiring to the drive
input.
VSD Com Fault
(VSD code 53)
Communications problems detected
reported by the VSD
Check connections to the VSD.
Check VSD control power and check
for board faults.
Drive Fault xx Problem reported by the VSD Refer to fault codes in table below
Drive fault codes are used for least-likely faults. The Supervisor will display these as "Drive Fault"
with a code number. If a keypad service tool is plugged into the drive, it will display the fault code
and the fault name shown in the first two columns.
Code Fault Possible Cause Solution
1 Overcurrent The variable speed drive has
detected a high current (>4xIn) in
its output due to:
• sudden heavy load increase
• short in the motor
• short in the cables to the motor
• unsuitable motor
Check loading.
Check motor.
Check cables.
2 Overvoltage The DC-link voltage has
exceeded its high limit due to:
• too short a deceleration time
• high voltage levels or surges in
the utility supply
Make the deceleration time longer.
Use a chopper and brake resistor.
Correct utility supply voltage (level
is too high).
Add input impedance to limit
surges.
3 Ground Fault
(Earth Fault)
Current sensing indicates that the
sum of motor phase currents is
not zero.
• insulation failure in motor or
motor cables
Remove faults from ungrounded
systems.
Check the motor and motor cables.
5 Charging Switch The charging switch was open
when the START command was
been given due to:
• faulty operation
• component failure
Reset the fault and restart.
Should the fault re-occur, contact
Sullair service
