■ Standard wiring diagram for pulse/analog input type
When performing position control, speed control, torque control of pulse/analog input type servo amplifier, terminals
used are different from each other. Please refer to the following wiring diagram for wiring.
● Position control(When 3-phase AC200V power supply is used)
*1 Differential line driver equivalent to AM26C31.
*2 This wiring diagram is for the input of differential line driver equivalent to AM26C31. The wiring diagram for
opencollector input is as follows:
*3 SG (signal ground) is short-circuited internally.
*4 The alarm will output for max. 5s when powering on the control loop.
*5 Wiring is different depending on whether to use an external regenerative resistor or a DC reactor.
