4. Line driver outputs of the encoder signals (C5)

The signal divided from the encoder signal is transferred to the host-controller through the line driver.

C5-1:Long line receiver

C5-2: photo coupler receiver

z On the host controller uses AM26LS32(or

equivalent) to make the receiver, must

connect the terminal resistance, the value is

220Ω～470Ω;

z Encoder signal (GND) of servo driver must

connect with the ground terminal on host

controller.

z On host controller use high-speed photo

coupler (e.g. 6N137); Current limiting resistor

is about 220Ω.

5. Open-collector output of encoder Z signal (C6)

The Z signal of the encoder is transferred to the host-controller through the open-collector circuit. Because the

width of the Z pulse is narrow, please use a high-speed photo-coupler to receive it.

C6: Open collector output of encoder Z signal

z 30V is the maximum voltage of external power supply; 50mA is

the maximum current output.
