Information on major components
The PPM utilizes small power resistors for preventing inrush current, and is connected serially to the charging
system. Because the opening/closing of the charging system may give significant impact on the system, the PPM
utilizes safety relays for state monitoring.

Regenerative discharge module (RDM)
The RDM prevents strong electricity components from being damaged by regenerative power generated by the
deceleration of the motor. It is composed of a board, regenerative discharge resistor, and a case.
