Cutting Unit Motors
The three cutting unit motors are identical 48 VDC, brushless, permanent magnet
motors. Each motor has its own on-board controller (T1: center cutting unit, T2:
left cutting unit, T3: right cutting unit). If a problem exists with any cutting unit
motor, a fault may have occurred that would be indicated by a fault code on the
InfoCenter Display. Before considering that cutting unit motor service work is
necessary, check for any existing fault codes that indicate problems with a cutting
unit motor; refer to
Machine Faults (page 3–7) . If a cutting unit motor is faulty,
there will likely be numerous fault codes that are listed by the InfoCenter display.
Because all the cutting unit motors used on the machine are the same, the
motors can be exchanged to help troubleshoot a problem. If the problem follows
the motor to the new cutting unit, the motor is likely the issue. If the problem
remains with the cutting unit, the issue is likely due to the cutting unit or electrical
components or wiring specific to that cutting unit.
To operate, the cutting unit motors require 48V logic power (supplied by the logic
relay) and a connection to the 48V power bus (supplied by the main contactor
when energized).
The cutting unit motor controller is not serviceable, and is best tested by using
the information provided on the InfoCenter display as described in the following
test procedure. Refer to
Appendix A (page A–1) for circuit wiring information.
Note: If a cutting unit motor is replaced for any reason, the machine software
must be updated; contact an Authorized Toro Distributor for assistance.
Testing the Cutting Unit Motors
The InfoCenter Display can be used to monitor the speed and current draw for
the cutting unit motors during machine operation; refer to
InfoCenter (page 5–10) .
1. Park the machine on a level surface, lower the cutting units and set the key
switch to the O
FF
position.
2. Set the function control switch to the N
EUTRAL
position.
3. Sit in the operator seat and set the key switch on the O
N
position.
4. Access the InfoCenter Diagnostics > PTO > Inputs screen.
