Note: 1. A 24-VDC power supply must be prepared.
2. Connect the varistor in parallel with the 24-VDC power supply terminal and the
GND terminal to suppress the surge voltage caused by turning the holding brake
ON and OFF.
3. Confirm pin numbers on the connector as well.
4. If using the servomotor to drive a vertical axis, configure a circuit to turn the
holding brake ON and OFF so that the movable section will not be pulled down
by gravity when the power supply of the SERVOPACK is turned OFF.
5. Turn the holding brake on the secondary side ON and OFF as shown in the
figure above. A varistor must be connected.
