Experimental Physics and
Im trying to use the same home (HVEL) and normal velocity (VELO) setting on a motion controller. I am attempting to set HVEL. Documentation says that
VBAS<=HVEL<=VMAX. I can set VBAS ok in my database, but VMAX will not set. Also, no matter what value I put into HVEL, I always end up with a HVEL=VBAS.
All my issues are at DB initialization. If i use Dbputs after initialization, the HVEL and VMAX fields set properly.
Ive also noted that if VBAS=VELO then the acceleration commands in device support are never called. Therefore I cannot set VBAS=VELO=HVEL in my database for initialization. I dont have a base velocity on this motion controller.
My solution thus far is to make VBAS, and HVEL slightly different from VELO.
Would appreciate any advice.
Thanks very much,
Dr. Mark Clift.
