6.14.6 Commissioning the digital spindle
Current controller Same procedure as for digital axes.
Speed controller Define the step function:
In MP3411.x, enter the maximum acceleration and start the step by
switching the spindle on.
Activate a spindle speed from the highest gear range.
With the integrated oscilloscope, record the nominal velocity value V (NOM
RPM), the actual speed value V (ACT RPM), and the nominal current value (I
NOMINAL).
Output a step by activating the Spindle On function (M03/M04).
Choose the height of the step function for a very low speed so as not to
overload the speed controller, i.e. so that I NOMINAL is not limited.
Increase the P factor (MP2500.x) until the system oscillates or no change is
visible. To edit machine parameters, press the MP EDIT soft key in the
Setup menu.
Calculate MP2500.x: MP2500.x = MP2500.x · 0.6
