Hardware in T1
detects a short
circuit in the power
stage and a phase-
to-phase short
circuit, phase B-
and phase B+
Everything is

1:
Short circuit in
motor
2:
Short circuit in
motor
wiring
harness
3:
Short circuit in
power stage
1:
Check the motor
•
Disconnect motor wiring
including sensor wires.
•
Insulation test. Check that the
coils are not electrically
connected to the chassis.
Replace M1 if the motor is not
isolated
2:
Check
the
motor
wiring
harness
•
Visual check of the motor wiring
harness. Check that there is no
contact between the pole
connections on the motor/motor
control. Search for contact and
damaged insulation on the
wiring harness.
•
Disconnect the motor wiring
harness at the motor control and
the motor and measure the
ohms of the wiring harness
between the phases and verify
that there is no contact.
3:
Replace T1

Hardware
protection in T1
detects a short
circuit in the output
to the brake (Q1)
The current
through the brake
exceeds the limit
values. Maximum
value = 5.95A,
continuous value =
3A
Everything is
stopped at once,
the parking brake
is activated, and
the main
contactor opens
High power
consumption or
short circuit
1:
Check for overcurrent or short
circuit:
•
Check the ohms and the
amperes of the component,
compare them to the setpoint
values if they outside the
accepted range.
•
Check the connections and
wiring harness for short-circuit.
•
Check that the component does
not seize or is jammed.
•
If points 1-3 are OK, it indicates
that the output stage is short
circuited - Replace the power-
supplying component
