Note
：
Tamagawa encoder does not
need CLK signal.
Nikon, Biss and Endat encoder
need CLK signal.
The shield layer must be
grounded safely.

2) CN5 definition
This terminal is used to input the servo motor encoder signal. It can be
connected to standard incremental encoder and ABZ incremental encoder
only. The schematic diagram of encoder terminal pins is below.
It is recommended to use the original accessory cable of the RT20 AC servo
