Power Module
As the name suggests, the power module handles the high-power output functions for the machine. It
receives its commands from the main machine controller via the CAN Bus network. The power module
provides basic motor control and protection, but the main machine controller controls the actual operation
commands for the motors.
The power module receives its logic power from the KSI relay, which is controlled by the main machine
controller. The power module has control of its own high-power input from the K2 relay. Unlike the
drive module, the power module has no direct inhibit input signals (i.e. seat switch or E-stop), except by
commands on the CAN Bus.
The power module has 2 types of outputs. The higher power outputs are non-reversing PWM control. The
lower power outputs are reversing PWM control. The power module is capable of monitoring the output
amperage from each of the outputs, and reporting this information to the main machine controller via the
CAN Bus.
