If a high-speed differential pulse or encoder is connected, PIN 24 (GND) of
controller and pin 13(GND), pin 25(GND) of drive should be connected together.
2.2.8.2 Wiring Reference for High-speed Differential Pulse
or Encoder Axis
If the low-speed differential pulse meets the speed requirement, using low-speed
differential pulse preferentially. Or if needs to use high-speed differential pulse,
do connect internal digital GND of controller with GND of high-speed pulse
interface of drive
.
