5. 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
 On the host controller uses
AM26LS32(or equivalent) to make the
receiver, must connect the terminal
resistance, the value is 220
Ω ～ 470 Ω ;
 Encoder signal (GND) of servo driver
must connect with the ground terminal
on host controller.
 On host controller use high-speed
photo coupler (e.g. 6N137); Current
limiting resistor is about 220
Ω .
6. 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.
