4. PARAMETERS
(4) When multiplying A-phase/B-phase output pulses by the value of the electronic gear
Set parameter No. PC13 to " 3 ".
The value resulted from multiplying the number of pulses per servo motor revolution by the value of the
electronic gear becomes the output pulse.
(a) Set the electric gear numerator in the A-phase/B-phase output pulses to parameter No. PA15.
(b) Set the electric gear denominator in the A-phase/B-phase output pulses to parameter No. PA16. Setting
0 to parameter No. PA16 is recognized as 1.
(Example) When using the HF-KN series servo motor
When parameter No. PA15 is set to "5600" and PA16 to "4096", the A/B-phase pulses
actually outputted are as follows.

POINT
Resolution per servo motor revolution depends on the servo motor as follows.
HF-KN series servo motor: 131072pulses/rev
HF-KP G1/G5/G7 servo motor: 262144pulses/rev
HG-KR G1/G5/G7 servo motor: 262144pulses/rev (when combined with MR-
JN- A servo amplifier)
