CSD5 Servo Drive

3-16 Wiring
(I/O) Input Circuit and
Interface
Describes the connection circuit for input from the host controller to
the servo drive.
Pulse Command Input Circuit
The drive receives the pulse output of host controller by position
command in position control mode.
Host controller can output pulse in line drive or open collector type.
Refer to the 5-10 page "Position Control Mode" for the servo drive
setting according to the selection.
