Do you have a VFD on a 3 phase motor for Lathe or Mill. 2 of my 4 machines follow that recipe. The Sheldon lathe, with a 30 some lb 8" 4 jaw mounted, can do the reversal at the bottom of a rigid tap with an overshoot of .25 turns at 100 rpm. The motor is a 1hp 3 phase about 50 years old I had to put bearings in. The 6040 motor died of bad bearings quickly, so both the 120 volt vfd and the motor were replaced with 250 volt equ's. No encoder, not enough cajones to tap a hole anyway, but sure did a nice job cutting out motor mounts and wrenches from 1/2" alu The other 2 machines have 90 volt, 9.7 amps at full song 1hp PMDC brushed motors and use Jon Elson's Pico Systems pwm-servo, both with big ugly 125 volt supplies and all get faster than expected control. Either supply is good for 30 amps surge. Jon's servo makes them both behave themselves well. They don't really have a choice with that kind of power banging on them. > 2.
