4.8.5 Encoder Feedback Output
The SV200 DC series servo drive can output encoder A/B/Z phase as differential output signals through the line driver. The output
signal is 5V, A/B signals are 10000 pulse/rev, Z signal is 1 pulse/rev.
The host must use the line receiver to receive these signals. Use twisted-pair wires for signal transfer.

NOTE: Please make sure the host controller and the servo drive are connected to a common
ground.
4.8.5.2 Z Phase Open Collector Output
On the SV200 drives, encoder signal Z uses open collector output circuitry. Due to the narrow bandwidth of encoder signal Z, please
use high speed opto-coulper circuitry for the host receiver.
