Hi Jerome,
Is your encoder connected and reading properly? You can verify this by
moving the motor shaft manually and then processing the motor record.
The encoder counts (.REP field) should go up and down accordingly.

Hello
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
