Wiring
DI wiring - input signals by relay or open collector transistor.
Conditions of DI On / Off:
3
ON: 15V - 24V; condition: input current = 8 mA.
OFF: 5V or below; the input current must not be higher than 0.5 mA.
C7: NPN transistor (SINK mode)
C8: PNP transistor (SOURCE mode)
C9: output for encoder position signal (line driver)
Note: it is suggested that you connect the two GNDs for the controller and servo drive in parallel when the
voltage deviation between the controller and the servo drive is too great.
