The regulator board is present only on the 8720MC-RPS (leader) unit.
Follower units, used in parallel configurations, have no regulator board and are
controlled by the regulator board on the leader unit.
The 8720MC-RPS regenerative power supply regulation is performed by a
microprocessor on the regulator board.
and components of the regulator board. The operation of the 8720MC-RPS
regenerative power supply is adjusted by the parameters set on the keypad.

Description
Based on the output of the current/voltage control loop, the regulator board sends
PWM gating signals through the power interface board to the power modules
(transistors), producing a pulse-width-modulated (PWM) waveform.
Sequence output signals are provided from the sequence signal terminal block
(TB3) of the regulator board to indicate the unit status.
A four-character seven-segment status indicator is used to monitor values,
parameter numbers, parameter values, and error codes. Six status indicators show
the display mode of the operation panel and the units of the monitored values.
ATTENTION: Only qualified electrical personnel familiar with the
construction and operation of this equipment and the hazards involved
should set jumpers and switches. Read and understand this manual in its
entirety before proceeding. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION: Do not press SW6 during operation. Also, do not alter the
setting of any jumpers and switches during operation. Failure to observe this
precaution could result in destruction of the equipment, severe bodily injury
or loss of life.
