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.
Cn-02 Bit 0 Rotation Direction
Selection
Set the direction of rotation.
Setting
Forward rotation is
defined as
0 counterclockwise
rotation when viewed
from the drive end.
Forward rotation is
defined as clockwise
1
rotation when viewed
from the drive end.
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.
