thanks for the answer Jeff,, now, how do we calculate base_period and servo period? Jeff Epler jep...@... writes: The latency-test runs the following realtime component: http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=src/hal/components/timedelta.comp Each time a realtime thread runs,

Thanks,,, I had tried to adjust the speed reference offset, the encoder still give the feedback but it small now maybe it's the noise from the power cable -- ThinkGeek and WIRED's GeekDad team up for the Ultimate

[Emc-users] zero speed problem with servo pack Yaskawa SGDM

2010-06-01 Thread ferdi andika
I use Yaskawa SGDM 02AD as servo pack and SGMAH as servo motor,, when I turned on the servo motor with zero speed reference (zero input reference),, the motor didn't move,,but the encoder still give feedback signal to emc2,, so the counter increased slowly (never stop),,, it turned an error to
