12. When not using the STO function, attach the short-circuit connector

came with a servo amplifier.

13. Configure a circuit to turn off EM2 when the main circuit power is

turned off to prevent an unexpected restart of the servo amplifier.

14. This diagram shows sink I/O interface.

15. The device can be changed with [Pr. PD04], [Pr. PD06], [Pr. PD08],

[Pr. PD10], [Pr. PD12], [Pr. PD14], [Pr. PD18], [Pr. PD20], [Pr.

PD22], [Pr. PD44], and [Pr. PD46].

16. These output devices are not assigned by default. Assign the

output device with [Pr. PD47] as necessary.

17. These devices are recommended assignments. The device can be

changed by [Pr. PD23] to [Pr. PD26], and [Pr. PD28].

18. DI2 and DI3 are assigned to the CN1-10 and CN1-35 pins by

default. When connecting a manual pulse generator, change them

with [Pr. PD44] and [Pr. PD46]. Refer to section 9.1 of "MR-J4-_A_-

RJ(Positioning mode) Servo Amplifier Instruction Manual" for

details of the manual pulse generator.

19. Supply + of 24 V DC to OPC (Power input for open-collector sink

interface) when input devices are assigned to the CN1-10 pin and

the CN1-35 pin. They are not used with source input interface. For

the positioning mode, input devices (DI2 and DI3) are assigned by

MR-J4-_A_-RJ
