6.20.7 Commissioning the digital spindle
Current controller The current controller is adjusted in the same manner as a digital axis, see
"Current controller" on page 1090.
Speed controller To activate the jump function, enter the following machine parameters:
Use MP_manualFilterOrder = 1 to activate the lowest filter order for the
Manual Operation mode. As a result, the nominal speed value is no longer
"averaged."
Start the step output by Spindle On.
Activate a spindle speed from the highest gear range.
Use the integrated oscilloscope to record the nominal feed rate (v nom), the
actual feed rate (v act), and the actual current value I (nom).
Output a step with 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 (nom) is not limited.
Increase the P factor of the speed controller (MP_vCtrlPropGain) until the
system oscillates or no change is visible. To change machine parameters,
press the END key in the oscilloscope and then the CONFIG EDIT soft key.
Calculate the input value for MP_vCtrlPropGain:
MP_vCtrlPropGain = MP_vCtrlPropGain ·0.6
