Hello Wesley, I am not sure this answers your question, but... The motor record has a SET field which can have values; 0:"Use" or 1:"Set". When the SET field is in the "Use" mode and user enters a new position, the motor moves to that position. If the SET field is in the "Set" mode and the user enters a new position the motor record redefines the current target positions (VAL/DVAL/RVAL) and the feedback positions (RBV/DRBV/RRBV) to the new value; i.e., it "sets" both the target and feedback positions to the new value. Hope this helps, Ron On 4/8/2011 11:25 AM, [email protected] wrote:
The motors that are an issue have no encoders or limit switches, so nothing for me to reference. Does anyone have a slick solution for "restoring" a motor's RBV? Perhaps, something like setting the offset to the last RBV after a reboot or crash. Thanks for your time. Wesley
