• SV.Pr45≠0 :￿

The pulse output resolution per one revolution can be divided by any ration

according to the formula below.￿

<Cautions>￿

• The setting of SV.Pr44>SV.Pr45 is invalid. (For the setting above, no division will

be executed.)￿

• Z-phase of the external scale is not reproduced.

Pulse output logic

0 to 3￿ You can set up the B-phase logic and the output source of the pulse output (X5 OB+

*

inversion

<0>

: Pin-48, OB– : Pin-49).

With this parameter, you can reverse the phase relation

between the A-phase pulse and the B-phase pulse by reversing the B-phase logic.

<Notes>

•For servo parameters which No. have a suffix of "*", changed contents will be validated when you turn on the control power.

•Parameters which default values have a suffix of "*" will be automatically set up during real time auto-gain tuning. When you change manually, invalidate the real-time auto-gain tuning first then set, referring to P.151, "Release of Automatic Gain Adjusting Function" of Adjustment.
