PWM ACQ. ERROR (MDI/LED code = 6)
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.
RPM HIGH (MDI/LED code = 0)
Cause:
This alarm occurs in Gen. Set versions when the speed exceeds the threshold
speed.
SENS MOT TEMP KO (MDI/LED code = 68)
Cause:
The output of the motor thermal sensor is out of range.
Troubleshooting:
Check if the resistance of the sensor is what expected measuring its resistance.
Check the wiring.
If the problem is not solved, replace the logic board.
SIN/COS D.ERR XX (MDI/LED code = 3)
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.
XX
DESCRIPTION
Cause
20
The module of the signal sin and signal cos is not
constant
Problem of the sensor.
A signal is clamped.
A signal is short or open
1
direction wrong
Swapped motor or sensor phases
2
direction wrong
Swapped motor or sensor phases
3
sensor not connected or without power
4
scaling error
check motor pulses or sensor periodicity
5
Error on module
A signal short or open
6
Error on module
A signal short or open
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.
SMARTDRIVER KO (MDI/LED code = 69)
Cause:
