1.5.3 CN5 Connector (Full-closed Loop)
Connect linear scale or encoder (A, B, Z format) to the servo and form a full-closed
loop. In position mode, the pulse command issued by the controller is based on the
control loop of the external linear scale. Please refer to Chapter 6.

NOTE
1. It only supports the encoder of AB phase and 5V voltage.
2. The application of full-closed loop: it supports the encoder of highest resolution 1280000 pulse/rev
(A
pulse number per motor revolution for a full-closed loop that corresponds to an optical signal with AB
(Quadrature) phase pulses (4x).).
