KX3 spindle running slow
« on: August 12, 2010, 05:04:50 PM »
Have just installed new KX3 with 5000rpm spindle the problem is that the spindle is running at about 50 % of the speed which is called for it maxes out at 2300rpm I altered the pulley 4 settings to 5000, ran auto cal in function config as the speed ramped up the revs lagged by about 50% I also entered a speed by MDI with same result checked spindle revs with digital rev counter.The cd contained a KX3 5000 profile version R3.041 which I used. Have only jogged other axis & they appear to be working OK. Hasanybody got any ideas please.

I had a problem with mine when I first set it up. It ran at max speed at anything over 2000 Rpm.

My numbers under Motor Tuning/Spindle are - Stepps Per 1175, Velocity 857.4, Accel 212.76596, Step Pulse 6.

Under pulley 4 I have mini speed 100, max speed 5000, ratio 1.

The number you want to mess with is the steps per number under motor tuning.
