ASDA-A2
C4-1: Pulse input (Line driver) can only apply to 5V power. Do not apply to 24V power.
 This opto-isolator is one-way input. Please be ensured the direction of
current of pulse input is correct.
C4-2: High-speed pulse input (Line driver) can only apply to 5V power.
Do not apply to 24V power.
 The high-speed pulse input interface of the servo drive is not the isolated
interface. In order to reduce the interference of the noise, it is suggested
that the terminal ground of the controller and the servo drive should be
connected to each other.
