About 8720MC-RPS Regenerative Power Supply |
Regulator Board
The Regulator Board exists only on master unit. The slave unit for parallel connection has no Regulator Board and is controlled by the microprocessor of the Regulator Board on the master unit.
The 8720MC-RPS Regenerative Power Supply regulation is performed by a microprocessor on the Regulator Board. The figure below shows the locations of the main components on the Regulator Board. The operation of the 8720MC-RPS Regenerative Power Supply is adjusted by the parameters set by the keypad.

Sequence Signal
Terminal Block (TB3)
•PWM Gating Signals
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
Sequence output signals are provided from the sequence signal terminal block (TB3) of the Regulator Board to indicate the unit status .
•Four-character Display and Six LEDs
A four-character seven-segment LED display is used to monitor values, parameter numbers, parameter values, and error codes. Six LEDs show the display mode of the operation panel and the units of the monitored values.

Jumpers and Switches
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 the reset button switch (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.
ATTENTION: Do not alter the settings of any jumpers not described in this manual. Failure to observe this precaution could result in damage to, or destruction of, the equipment.
The jumpers JP1 to JP3 and the switches SW6 and SW7 are set before shipment from factory. If you need to change the jumpers and/or switch settings, read and understand the following description of these jumpers and switches before proceeding.
•Jumper JP1 to Enable Operation
Short this jumper to start switching operation of transistors of the 8720MC-RPS Regenerative Power Supply when the RUN sequence input is enabled. This jumper should always be kept closed.
•Jumper JP2 to Enable Inspection Mode Keep this jumper open always.
•Reset Switch SW6
Pressing this switch resets the CPU.
Important: Do not press the reset switch SW6 during operation.
•Switch SW7 to Enable Base Block
This switch is used to stop switching of transistors that produce PWM waveform by interrupting the base signal from the Power Modules. To interrupt the base signal, turn the switch to the OFF side.
As shown in the figure below, SW7 consists of four switches, and SW7-1 to SW7-3 can be allocated to the master unit and slave units 1 and 2. In the case of a master with paralleled slave units, it is possible to interrupt the base signal of each unit by turning the corresponding switch to the OFF side. SW7-4 must always be kept to the OFF side.

About 8720MC-RPS Regenerative Power Supply |
When two units are connected in parallel, turn the switches SW7-1 and SW7-2 to the ON side, and when three units are connected in parallel, turn the switches SW7-1 through SW7-3 to the ON side.

Keep SW7-4 always to the OFF side.
When the switch is turned to the OFF side, the base signal is interrupted, and the unit will be in the OFF condition.
When the switch is turned to the ON side, the base signal is kept ON, and PWM switching will continue.
