2.4 Elimination of Heat
⚫
CS-D508 reliable working temperature should be no more than 60
℃
(140
°
F)
⚫
It is recommended to mount the drive vertically to maximize heat dissipation. Mount a cooling fan nearby if necessary.
⚫
If multiple CS-D508 drives are installed, it is suggested to keep a minimal 30mm (12 inches) between two of them.
3. Connections / Pin Assignments and LED Indication
CS-D508 closed loop stepper drive has 5 connection blocks from P1 to P5 (see figure 2).

Pinout Definitions
There are 3 control signals for pulse, direction, and enable. See the following table for details.

Details
PUL+
I
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 and ENA signals).
(4).
Pulse width
should be set to 2.5μs or longer.
PUL-
I
DIR+
I
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).
Minimal DIR signal setup time should be at least 5μs.
(4).
You can reverse the default rotation
direction by toggling the SW5 DIP switch.
DIR-
I
ENA+
I
Enable signal: This signal is used for enabling/disabling the drive. High voltage level of 4.5-5VDC
(NPN control signal) for enabling the drive and low voltage level of 0-0.5VDC for disabling the
drive. PNP and Differential control signals are on the contrary, namely Low level for enabling.
By default this signal is left
