Soft Start for Spindle Motor G Code Routine

4/2/2015· The soft start feature appears to emulate pushing of the front panel up arrow buttons and is set in firmware. It is far too slow for the spindle to come up to full speed of say, 3000rpm. The original boards do not have a soft start feature and this places a lot of stress on the spindle motor and belt when a speed of 3000+rpm is selected under G Code Control.Why We Need to Install a Starter with a Motor? Electrical .The motor will not start to run at this stage because there is no back E.M.F in the motor. The back E.M.F of the motor is reached at full rate when motor is running at full speed and rated load.
