6 0: Servo motor CCW rotation at positive speed
1: Servo motor CW rotation at negative speed
7 0: Servo motor CCW rotation in positioning address increase direction
1: Servo motor CW rotation in positioning address decrease direction
Only 00h or C0h can be set. Values other than 00h and C0h cannot be set.
(2) Position encoder resolution (608Fh)
Index Sub
0
608Fh 1
2
Default
1
Encoder resolution is returned with Encoder increments (608Fh: 01h). 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 (6091h)
Index Sub
0
6091h 1
2
Default
2
1
Set the electronic gear. Refer to [Pr. PA06] for the settable values. In the cyclic synchronous mode,
always set 1 for Motor revolutions (6091h: 01h) and Shaft revolutions (6091h: 02h).
