Divided encoder signals are output.
Always connect these signal terminals when a position loop is formed in the host control-
ler to perform position control.
Set a dividing ratio in the following user constant.
Dividing ratio setting
The dividing ratio setting is not relevant to the gear ratio setting (Cn-24, 25) for the
electronic gear function of the Servopack for position control (SGDA-jjjP).
