GSK980TDb CNC User:

Hi, the max speed in GSK980TDb parameter was set 1600rpm, now we have changed it to 2000rpm, the strange thing is now the spindle only runs 1400rpm, why this happen? The lathe machine uses frequency inverter.

If the parameter sets 1600rpm as the max speed, it means when the speed is 1600rpm, the output voltage is 10V, if change 1600rpm to 2000rpm, then 2000rpm = 10V, so it requested to change the frequency inverter's parameter, to make it 10V when the speed is 2000rpm.
