11.6 Restart function
When the axis has been stopped by the axis stop signal during operation under
position control or speed-position switching control, you can resume positioning control
from where it had stopped by giving " Cd. 4 Restart request".
The following will be described for the "restart function".
[1] Control details
[2] Precautions for control
[1] Control details
(1) Restart during position control
Setting "1: With restart request" in " Cd. 4 Restart request" when "Md. 4 Axis
operation status" is "Stopped" resumes position control from the stop position to
the end point of the positioning data where the axis had stopped, independently
of the absolute or incremental system.
[Example for incremental system]
The following is the operation performed when the axis is stopped during
execution of position control (1-axis linear control) at the axis 1 movement
amount of 600 and a restart request is executed after the axis stop signal
turns OFF.

(2) Restart during speed control
Speed control is resumed at the speed used before a stop made by the axis stop
signal [Y10 to Y17].
(3) When restart is not made during position control
When "Md. 4 Axis operation status" is "Stopped", turning ON the positioning start
signal [Y8 to YF] starts position control from the current stop position.
[Example for incremental system]
The following is the operation performed when the axis is stopped during
execution of position control (1-axis linear control) at the axis 1 movement
amount of 600 and position control is started after the axis stop signal turns
OFF.
