9.3.12 Factor Group Objects

(1) Polarity (P24702)
The rotation direction selection can be set. Only 00h, C0h, or E0h can be set. Values other than 00h,
C0h, and E0h cannot be set.
Refer to section 8.5 for details.

(2) Position encoder resolution (P24719)
Encoder resolution is returned with Encoder increments (P24719.0). When the linear servo motor is
connected, the virtual resolution per revolution is returned. When the fully closed loop system is used,
the number of load-side pulses per servo motor-side revolution is returned.

(3) Gear ratio (P24721)
Set the electronic gear. Refer to [Pr. PA06] for the settable values. In the cyclic synchronous mode,
always set "1" for Motor revolutions (P24721.0) and Shaft revolutions (P24721.1).
