I am having a problem with my TC-22 w/dx-32 control. 2 speed gearbox on the spindle. When in low gear everything works perfect. When in high, say 2500 rpm, the spindle faults when the spindle shuts off. Seams like it tries to decelerate to 0 rpm instantly. Spindle goes from 2500 to 0 in less than a sec. then coasts and kicks out. I looked at Parameter 48 (spindle Acceleration/Deceleration Rate) and its value is "0" My book doesn't give me a value or formula, so I have no idea what this should be set at. Any sugestions would help. Thanks
