CAN Bus
The drive controller communicates with the main machine controller via the CAN Bus. The drive controller
transmits error codes to the main machine controller. The main machine controller sends several messages
to the drive controller that regulate machine speed mode. The drive controller has three speed setting
modes:
1. Transport - This is set at 100% of the total speed potential.
2. Scrubbing Speed - (Battery models only) This is set at 80% of the total speed potential. The user can
override the scrubbing mode by pressing the speed switch.
3. Hopper Up - This is set at 50% of the total speed potential for safety reasons.
The following table explains what conditions dictate the speed mode which is used.
