You mean SERVO_PERIOD = 4000000 ?one test could be to slow down the servo thread, maybe the drive has limitations.
try 4000000 (4ms) for servo-thread and apptimeperiod like it is in the twincat setup.

yes,
ini file : SERVO_PERIOD = 4000000
and
ethercat_conf : apptimeperiod = 4000000
they have to be equal.

It doesn't work even if you change the values to 4000000
Can you recommend a tutorial on how to write a hal component to drive motors?
