9) Connector for Pulse Train Control [Refer to Chapter 3.3 Operation in Pulse Train Control

Mode.]

The pulse train I/O connector is used in the pulse train control mode.

Feedback Pulse is also effective in Positioner Mode

10) PIO Connector [Refer to 2.3.4 Connection of PIO.]

The PIO connector is used for control I/O signals.

11) Operation Mode Setting Switch (MANU/AUTO)

This switch is used for interlock so that a moving command from PIO (PLC) and a command

from the teaching tool such as a PC may not be issued at a time.

AUTO ··· Allows auto operation by PIO signals. The teaching tool such as a PC can only

operate the monitor.

MANU ··· Allows the teaching tool such as a PC to operate the controller.

12) SIO Connector (SIO) [Refer to 2.3.7 SIO Connector Connection.]

The SIO connector is used to connect the controller with a teaching tool such as PC software

or a gateway unit through a proper communication cable.

13) Brake Release Switch (BK RLS/NOM)

For the actuator equipped with a brake, the switch is used to release the brake forcibly.

Warning : Always set the switch to “NOM” in normal operation.

The brake would not work even with the servo OFF condition if the switch

is on the RLS side. In the vertical oriented mount, the work may drop and

cause an injury or the work to be damaged.

14) Brake Power Supply Connector [Refer to 2.3.1 Wiring of Power Circuit.]

For the actuator equipped with a brake, the connector supplies the power (24V DC) to

release the brake.

15) Encoder Connector (PG) [Refer to 2.3.3 Connection to Actuator.]

This connector is used to connect the encoder cable of the actuator.

16) Absolute Battery Connector

In the absolute specification, the connector is connected with the absolute battery.
