3.8 Control and functions of Input and output signals of Remote I/O Mode

210

[Operation of Slider Type/Rod Type Actuator]

1) With the ST0 signal being ON, the actuator moves toward the mechanical end at the home

return speed.

The moving speed is 20mm/s for most actuators but less than 20mm/s for some actuators.

Check the instruction manual of actuator.

2) The actuator is turned at the mechanical end and stopped at the home position. The moving

distance is the value set by Parameter No.22 “Home return offset level”.

(Note 1)

Caution: In the home reverse specification, the actuator moves in the reverse direction.

Make sure to refer to Section 7.2 [12] when a change to Parameter No.22

“Home Return Offset Level” is required.

Note 1: It moves for the offset amount after the encoder Z-phase is detected.

[Operation of Rotary Actuator]

(1) 300°Rotation Specification

Home = 0°

Home sensor

1) By HOME Signal being on, the rotary part turns in CCW (counterclockwise) from the view of

load side. The velocity is either 20deg/s or 5deg/s. (It depends on the setting of each

actuator.)

2) At the home sensor input, the actuator is turned in the reverse direction and stopped at the

home position. The rotation angle is the value set by Parameter No.22 “Home return offset

level” after the detection of phase Z.

Caution: Make sure to refer to Section 7.2 [12] when a change to Parameter No.22

“Home Return Offset Level” is required.
