-- Motor move only one direction / Motor 6.2.2 / OMS58-4S / servo-tar 300 --

[jerome HOSSELET <jerome.hosselet@ires.in2p3.fr>]

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: <3AC208CF.A488DC02@psi.ch>)
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
