The Kawasaki MC power supply unit 50632-0022R03 mainly consists of a power board 1WU 50999-0415R00 and a control board 1VH 50999-0185R03.

The power supply board of the MC power supply unit uses AC210V to generate PN power, control the absorption of regenerative energy, and generate brake power.

Main functions of MC unit power board:

1. Execute sending/receiving signals with 1VH board (MC unit control board 50999-0185R03);

2. Output the PN power generated by AC210V to the servo amplifier unit;

3. Control the surge current by receiving instructions from the 1VH board;

4. Monitor the PN voltage and provide feedback to the 1TV board;

5. Control the absorption of regenerative energy. Colleague, provide feedback on the thermal switch status of the regenerative energy absorption resistor to the 1TV board;

6. Monitor the 20V power supply voltage of the power module and provide feedback to the 1VH board;

7. Monitor the temperature of the thyristor module that generates PN power and provide feedback to the 1TV board;

8. Monitor the internal 6.9V power supply voltage and provide feedback to the 1VH board.
