3) Setting Reverse Rotation Mode:
Reverse rotation mode can be set in either of the following two ways. Normally, method 1
is easier to use.
a) Method 1: Setting Memory Switch
Set bit 0 of memory switch Cn-02 to select reverse rotation mode.

Setting: 0
For Speed/Torque Control
and Position Control
Set the direction of rotation.
Setting Meaning
0
Forward rotation is
defined as
counterclockwise
rotation when viewed
from the drive end.
(Standard
setting)
1
Forward rotation is
defined as clockwise
rotation when viewed
from the drive end.
(Reverse

mode)
b) Method 2: Shorting the Wiring in the 2CN Connector
Reverse rotation mode can be set for the 2CN
connector for the encoder. This method is used
to standardize user constant settings without
using the memory switch.
In this case, reverse rotation mode is set
regardless of the memory switch setting.
