4.2.3 Using the Encoder Signal Output
Encoder output signals divided 1 inside the SERVOPACK 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 follow-
ing circuit diagram.
1 Dividing
Dividing means converting an input pulse train from the encoder mounted on the servomotor accord-
ing to the preset pulse density and outputting the converted pulse. The units are pulses per revolution.
