Appendix

15. Pausing of Operation

Description

Use a declarative command HOLD to pause the moving axis via an external input.

How to Use

You can interrupt and pause the movement of the axis (= cause the axis to decorate to a stop) by

declaring a HOLD command in the program. While HOLD is input, all movement commands issued in the

same program are paused (all moving axes decelerate to a stop).

Example of Use

HOLD 20 Declare that if general-purpose input 20 turns ON, a pause process will be performed.

Application

In addition to an input port, you can also specify a global flag in operand 1 of the HOLD command. It is

also possible to implement a pause from other program using a global flag.

When operand 2 is used, you can select a desired pattern of input signal as well as a stopping pattern.

0 = Contact a (Deceleration to a stop)  Same as when operand 2 is not specified

1 = Contact b (Deceleration to a stop)

2 = Contact b (Deceleration to a stop, followed by servo OFF  Drive power is not turned off)

Note

If the axis was paused during home return, when the operation is resumed the home return sequence will

be performed from the beginning.
