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? Abdalla Al-Dalleh Control Engineer SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) Fax: +96253511423 abdalla.ahmad at sesame.org.jo |
