I/O Signals
I/O signals are described below.
Divided encoder signals are output.
Always connect these signal terminals when a position loop is formed in the host
controller for position control.
Set a dividing ratio at the following parameter.
The dividing ratio setting is not related to the gear ratio setting (Pn202 and 203) for
the servo amplifier electronic gear function during position control.
