-
Through the TESTER function, check the states of the inputs are
coherent with microswitches states.
-
If the problem is not solved, replace the logic board.
INIT VMN HIGH XX
(MDI/LED code = 31)
Cause
Before closing the LC, the software checks the power-bridge voltage without
driving it. The software expects the voltage to be in a “steady state” value.
If it is too high, this alarm occurs. The hexadecimal value “XX” identifies the
faulty phase:
81: phase U
82: phase V
83:
phase
W
Troubleshooting
-
Check the motor power cables.
-
Check the impedance between U, V and W terminals and -B terminal of
the controller.
-
Check the motor leakage to truck frame.
-
If the motor connections are OK and there are no external low
impedance paths, the problem is inside the controller. Replace it.
INIT VMN LOW XX
(MDI/LED code = 30)
Cause
Before closing the LC, the software checks the power-bridge voltage without
driving it. The software expects the voltage to be in a “steady state” value. If
it is too low, this alarm occurs. The hexadecimal value “XX” identifies the
faulty phase:
01: phase U
02: phase V
03:
phase
W
Troubleshooting
-
Check the motor power cables.
-
Check the impedance between U, V and W terminals and -B terminal of
the controller.
-
Check the motor leakage to truck frame.
-
If the motor connections are OK and there are no external low
impedance paths, the problem is inside the controller. Replace it.
IQ MISMATCHED
(MDI/LED code = 24)
Cause
The error between the Iq (q-axis current) setpoint and the estimated Iq is out
of range.
Troubleshooting
Ask for assistance to a Zapi technician in order to do the correct adjustment
of the motor parameters.
LC COIL OPEN
(MDI/LED code = 22)
Cause
This fault appears when no load is connected between the NMC output
A12
and the positive voltage (for example the KEY voltage).
