(1) Setting "1: With restart request" in " Cd. 4 Restart request" when " Md. 4 Axis
operation status" is other than "Stopped" results in the "Restart not possible"
warning (warning code: 11).
(2) If "1: With restart request" is set in " Cd. 4 Restart request" when the axis
stop signal [Y
(error code: 102) occurs and a restart is not made.
(3) If the positioning data is changed after the axis has been stopped by the axis
stop signal [Y
(4) The restart function is not performed in the following cases.
(The "Restart not possible" warning (warning code: 11) occurs.)
• During OPR control
• During JOG operation
(5) For speed-position switching control, the axis is always restarted by speed
control whichever speed control or position control is used for the operation
before the axis is stopped by the axis stop signal.
The following shows operations under speed-position switching control after
restart.
(a) When the speed-position switching signal (CHG) is OFF at restart
The axis is started with speed control, and position control of the
movement amount set in " Da. 6 Positioning address/movement
amount" is executed from the position where the speed-position
switching signal is turned ON.
