Setting Spindle RPM (Mach4)

Problem: Not going the correct RPM?

Is the spindle encoder configured correctly?


Is it linear?

Set Max Frequency

If you cannot locate the motor’s frequency, the name plate should tell you how many poles there are on the motor.
Using the motor’s maximum RPM and its number of poles, you can calculate the frequency with the formula below.
Base Frequency = Max RPM * Number of Poles / 120
