Motor Controller
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.
The motor controllers also control the valve
outputs and machine options such as flashing
beacon, travel alarm, etc.
Refer to Section 5,
Fault Codes for a list of fault
codes and additional information.
