Hi,

I am trying to test my Mesa boards (5i23 and 7i33) with my servo motors.
But there is an unexpected problem that EMC2 can't control servo. When I
jog, servo motor tuns with oscillation and when i stop jogging, it
continue oscillation some seconds more then stop. My servo motor has
resolver with 24000ppr and i am getting differential encoder output from
its driver. Also servo driver has own control loop inside, i have tried
to disable its control loop but i could only set "target loop gain" to
1. Also i have tried to change PID values of EMC2.
My servo period is recommended (1000000ns), and PWM/PDM frequency is
recommended (100000 Hz). Following Error is 0.5, and Minimum Error is
0.01. I don't know why it happens but i guess two control loop is
overlapping. Do you have any idea about my this problem? Am i using too
slow servo-thread? Did anyone have tried to use Toshiba Servo Driver
(VLASX-012P2) with EMC2?

Thanks.
