Internal 24V
power supply
COM- is the ground terminal of the 24V power. Its capacity is
100mA. If the actual load is higher than this value, the user
shall provide the power supply by themselves.
GND 5,6,8,19,35 Signal ground
The ground of the internal power supply (except the 24V
power supply) of the servo drive, it is also the ground of the
phase A/B/Z open-collector signal of the encoder and the
analog output signal. It is isolated from COM-.

DI input
common port
If DI is active-low (0V), COM+ connects to internal 24V
power (pin 40) or external DC power (12V~24V);
If DI is active-high (12V~24V), COM+ connects to the
reference ground of corresponding signal.

If external DC power 12V~24V is used, power 0V is
connected to this terminal.
