Adjusting the spindle synchronous control

(1) Confirming the default parameters
Confirm that the parameters are correctly set according to the machine specifications. The
parameters are set with the following conditions for spindles used for synchronous control.
1) Position loop gain
The same value must be set for the spindle drive units used for synchronous control.
Spindle synchronous position loop gain
Spindle synchronous position loop gain 2 : SP189
Spindle synchronous position loop gain 3 : SP190
