I'm a beginner on EPICS. I try to command a brushless motor with motor 6.2.2 through OMS58-4S VME card on EPICS 3.14.8.2 (brushless motor is not a stepper motor). Actually, I can only move the motor in one direction. I use for debug a ASCII ligne command. I found on tech-talk (References: <[email protected]>) http://www.aps.anl.gov/epics/tech-talk/2001/msg00140.php that the first command must be: "AT HE KP.1 KD.3 KI0 LP0 HN" After that i send a move relative positive or negative. But the motor move always in one direction. Asking QA command we show a direction have a correct value AT MR20000 GO AT QA -> OMS58>PNNH< AT MR-20000 GO AT QA -> OMS58>MNNH< I monitor also analog signal (output voltage for servostar) on output OMS58-4S. I see for MR20000 a positive voltage and for MR-20000 I expect a negative voltage but i see a positive voltage more larger than the first. Can somebody help me ? or have same troubles ? thanks per advance Jerome HOSSELET begin:vcard fn:Jerome HOSSELET n:HOSSELET;Jerome org:CNRS / IPHC;Electronique / Informatique adr:;;23 rue du loess;Strasbourg;;67000;FRANCE email;internet:[email protected] title:Assistant Ingenieur tel;work:03 88 10 65 30 tel;home:03 88 xx xx xx tel;cell:06 60 xx xx xx note;quoted-printable:Assistant Ing=C3=A9nieur =C3=A0 l' IPHC :=0D=0A= - Projet CMS=0D=0A= - Projet SPIRAL 2 x-mozilla-html:FALSE url:http://ireswww.in2p3.fr/ version:2.1 end:vcard
