11-1 Motor Controllers

There are two drive motor controllers located inside
the non-steer axle, one for each drive motor. When
viewed from the non-steer end of the machine, the
right side motor controller is the "master" and the
left side motor controller is the "slave." The master
motor controller controls the right drive motor and
the function pump. The slave motor controller
controls the left side drive motor and auxiliary
power unit. The motor controllers are also AC
voltage inverters which take the DC voltage from
the system batteries and convert the voltage to AC
power for the drive motors. The motor controllers
are in communication with the turntable controller
(TCON) and the platform controller (PCON) which
are able to communicate operating or fault
information to the LCD display at the platform
controls.
