(2)Motor ID No.
Select the motor ID No. of the servo motor to be used, according to the
motor model and drawing number (the middle four digits of
A06B–XXXX
–BXXX).
For the motor ID No. of the servo motor, refer to the parameter manual
for servo motors.
NOTE
Servo axes are controlled in groups of two axes. So, for
successive servo control numbers (odd number and even
number), motor type number unified for servo HRV1 or for
servo HRV2 or HRV3 must be specified.

NOTE
1 For both F⋅FG number and denominator, the maximum
setting value (after reduced) is 32767.
2 αi pulse coders assume one million pulses per motor
revolution, irrespective of resolution, for the flexible feed
gear setting.
3 If the calculation of the number of pulses required per motor
revolution involves π, such as when a rack and pinion are
used, assume π to be approximately 355/113.
