Experimental Physics and
Industrial Control System

Hi

 

We want to use the sscan module to scan a coordinate motion for a slit system. The slit’s gap and center are calculated using two transform records, forward and reverse (COPT = Always). When starting a scan, if the scan’s start point is far from the current position, the scan goes quickly through the scan points and does not wait for the target set point unlike when using a motor record where the scan waits for a callback indicating the positioner is done moving. If we relatively increase the positioners’ settling time, the scan goes through all scan points.

 

I would like to ask, is there a way to tell the scan record from the transform record that the positioner is done moving and go to the next step of the scan?
