PWM
ACQ.
ERROR
Cause
This alarm occurs only when the controller is configured to drive a PMSM and the
feedback sensor selected in the HARDWARE SETTINGS list is ENCODER
ABI + PWM. The controller does not detect correct information on PWM input at
start-up
Troubleshooting
- Re-cycle the key.
- Check the sensor in order to verify that it works properly.
- Check the wiring.
- If the problem occurs permanently it is necessary to substitute logic board
165
SHORT
CIRCUIT
KO
Cause
The HW dedicated to detect faults on power bridge does not work properly
Troubleshooting
- Replace the controller.
166
SHORT
CIRCUIT
Cause
The controller continuously checks that the Three-phase bridge works properly and
that a short-circuit between motor phases is not present.
Troubleshooting
- Check that motor phases are correctly connected.
- Verify that motor phases are not shot-circuited.
- Replace the controller.
- In case the problem is not solved, replace the motor.
167
IMS
ERROR
Cause
At start-up, the controller checks the presence of IMS board. If the IMS board is
not well connected, this alarm appears.
Troubleshooting
- Replace the controller.
168
SIN/COS
D.ERR.X
X
Cause:
This alarm occurs only when the controller is configured as PMSM and the
feedback sensor selected is sin/cos. The signal coming from sin/cos sensor has a
wrong direction. The hexadecimal value
“
XX
”
facilitates Zapi technicians
debugging the problem
Troubleshooting:
Check the wirings.
If the motor direction is correct, swap the sin and cos signals.
If the motor direction is not correct, swap two of the motor cables.
If the problem is not solved, contact a Zapi technician

ENCODE
R
D.ERR.X
Cause:
This alarm occurs only when the controller is configured as PMSM and the
feedback sensor selected is the encoder. The A and B pulse sequence is not correct
