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

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 parameter settings without using
the memory switch.
In this case, reverse rotation
mode is set regardless of the
memory switch setting.
