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).
Test the MIDI fuse for the 48V bus
voltage to the controller (SC5 fuse
under seat, SC6 fuse under left side
cover).
Measure the voltage at the motor
connector to determine whether the
voltage is low, or the controller is
measuring low.
Check the 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).
