This is the reference point of electric potential for Analog
command voltage input to Pin No.32.
■ TIP
If the analog velocity command circuit of the host controller
is isolated from 24V control power supply, connect A_GND
to signal ground of the host controller, not to GND of control
power, If the analog velocity command circuit is not isolated,
connect A_GND to GND of control power.
