5. PARAMETERS
To rotate the servo motor at 3000r/min in the open collector system (200kpulse/s), set the electronic gear
as follows
CMX N

POINT
In addition to the setting method using the electronic gear given here, the
number of pulses per servo motor revolution can also be set directly using
parameter No. PA05. In this case, parameter No. PA05 is the "Number of pulses
per servo motor revolution as viewed from QD75".
