Setpoint acceptance To
The "setpoint transfer to" parameter defines the time when the speed setpoint of the NC
position controller is accepted by a DP slave S120.
Note
You are strongly recommended to use the same value for the time of setpoint acceptance To
for all DP slaves S120, in particular if the axes interpolate.
NOTICE
The following condition must be observed for the time of setpoint value transfer TO:
DP cycle >= setpoint accept. >= equidist. master cycl. component + base time
Dialog: Continuation
Comparison
The values of the current DP slave S120 displayed in the "Cycle synchronization" tab are
transferred to all the other DP slave S120 of the configuration via the Comparison interface.
This adjustment must be carried out at the end, and the dialog box must then be confirmed
with OK.
Dialog: End
OK
