3. Connections and LED Indication
A CS-D403 closed loop stepper drive has 5 connection blocks from P1 to P5 (see figure 2).

3.1 Connector P1 – Control and Digital Output Connections
3.1.1 Pin Assignments of P1
The P1 connector in Figure 2 contains connections for control signals and a configurable digital output.
a) Pinout Definitions
There are 3 control signals for pulse, direction, and enable. See the following table for details.

Pulse signal:
(1)
. In single pulse (pulse & direction) control mode, this input represents pulse
signal. A pulse signal is active at the rising or falling voltage edge (set by DIP switch SW8).
(2).
In double-pulse (CW/CCW) control mode (set by DIP switch SW7), this signal input
represents clockwise (CW) pulse, and is active at both high voltage level and low voltage level.
(3).
4.5-5V for voltage HIGH, 0-0.5V for voltage LOW (same for DIR signals).
(4).
Pulse
width should be set to 2.5μs or longer.

Direction signal:
(1).
In single pulse (step & direction) control mode, this signal’s low and high
voltage levels represent the two directions of motor rotation (e.g. clockwise and
counterclockwise).
(2).
In double-pulse (CW & CCW) control mode, this signal represents
counterclockwise (CCW) rotation. It is active at both voltage high level and low level.
(3).
