Overspeed a Motor
If you want to command your spindle motor or grinding wheel to go faster than the base frequency,
command the spindle to go max RPM and use a tachometer to measure the speed. Then use the
following formula to calculate your new Max Output Frequency (Hb105):
Desired Max RPM * Current Max Frequency / Current Max RPM = New Max Frequency
For example, if your Current Max Frequency is 60 and you measure the spindle runs 1030 RPM but
you actually want it to go 1515 RPM, calculate your new Max Frequency as follows:
1515 * 60 / 1030=88 Hz.
Make sure to recalibrate your RPM feedback and your spindle speed as both shown below.
