5.2.3 Using the Encoder Signal Output
Encoder output signals divided inside the servo amplifier 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.
Phase A
Phase B
Phase C
P: Indicates twisted pair wires.
Note: 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
(ppr).
