Using the Encoder Signal Output

Encoder output signals are divided inside the servo amplifier and can be
output externally. These signals can be used to form a position control
loop in the host controller.

The output circuit is for line-driver output. Connect each signal line
according to the following circuit diagram.
Note: Dividing means converting an input pulse train from the encoder mounted on the servomotor according
to the preset pulse density and outputting the converted pulse. The units are pulses per revolution (PPR).
I/O Signals
I/O signals are described below.
Output PAO CN1-33
Output /PAO CN1-34
Output PBO CN1-35
Output /PBO CN1-36
Output PCO CN1-19
Output /PCO CN1-20
Divided encoder signals are outputs; therefore always connect these signal terminals
when a position loop is formed in the host controller for position control.
Set a dividing ratio using the following parameter: PG Dividing Ratio Pn201
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.
