I have a 2.2 kw HY VFD and 2.2kw 24,000 rpm water cooled spindle. I use PWM control via a PMDX 126/PMDX 107. I would like to reduce the time it takes to get the spindle up to the set speed. Currently, it takes just under 10 seconds to get from 0 to 16,000 rpm. I have a ramp up delay set in Mach4, so no problems when cutting. Is there a parameter I can set, and if so, what is the range of settings to safely use?

Thank you in advance.
