I ran into a similar problem with my Bergerda drive the first time I used it on the X axis. The servos must be configured in velocity mode (Hiwin Control 2). Not position mode (Hiwin Control 1). (Page 16 of the Hiwin D2 manual). https://www.youtube.com/watch?v=cx-kAqdwceU
Here's it working properly. https://www.youtube.com/watch?v=43liAVILgHY John > -----Original Message----- > From: Leonardo Marsaglia [mailto:ldmarsag...@gmail.com] > Sent: January-24-23 7:40 AM > To: Enhanced Machine Controller (EMC) > Subject: [Emc-users] Servo motor in step mode reaches position after LCNC > > Hi guys, hope you are all doing well. > > My brother is changing some stepper motors to servos from a machine with > LCNC 2.4.3 and a mesa 5i20.
