Description
SC5, SC6 Two traction
motor phases
are shorted
together but
not shorted
to ground in
the indicated
traction motor
controller or
motor.
The motor is
SC5, SC6
not responding
to the power
setpoint in
the indicated
traction motor.
SC5, SC6, The traction
T5 motor measures
the 48V logic
voltage at less
than: 38V (SC5,
SC6) or 32V for
T5
SC5, SC6, The traction
T5 motor measures
the 48V logic
voltage at
greater than:
65V (SC5, SC6)
or 67.5V for T5

Page 3–23 Troubleshooting: Battery Charger Error and
Verify that the U, V, and W motor
phase cables are in the correct order.
Check the motor power cables.
Replace and program the traction
motor controller (contact an Authorized
Toro Distributor for assistance).
Cycle the key switch.
Use the InfoCenter to calibrate the
traction motor controller.
For SC5, calibrate the traction pedal
first, then the traction motors.
For SC6, calibrate the traction motors.
Replace the traction motor. Use the
InfoCenter to calibrate the traction
motors.
Verify that the U, V, and W motor
phase cables are in the correct order.
Verify the speed feedback sensor
(sin-cos) is wired correctly.
Use the InfoCenter to calibrate the
traction motors.
Contact an Authorized Toro Distributor
or the Toro Technical Assistance
Center and report that this fault
occurred.
Measure the voltage at the motor
connector to determine whether the
voltage is low, or the controller is
measuring low.
Check the 48V battery voltage.
Inspect the wiring to the motor.
Replace the traction motor.
For SC5 and SC6, use the InfoCenter
to calibrate the traction motors.
For T5, program the traction motor
(contact an Authorized Toro Distributor
for assistance).
Measure the voltage at the motor
connector to determine whether the
voltage is high, or the controller is
measuring high.
Check the 48V battery voltage.
Inspect the wiring to the motor.
Replace the traction motor.
For SC5 and SC6, use the InfoCenter
to calibrate the traction motors.
For T5, program the traction motor
(contact an Authorized Toro Distributor
for assistance).
