1. Introduction
Leadshine CS-D508 is a closed loop stepper drive designed to solve the loss of step problem in open loop stepper
control systems, thus increase system reliability at minimal cost increase. It implements advanced control algorithm of
Leadshine based on its tens of years’experience in stepper and servo controls. The CS-D508 is highly reliable and
affordable and performs excellent in many industrial applications such as CNC, medical, electronics, packaging...
The CS-D508 can power 2-phase NEMA 17, 23, and 24 stepper motors with incremental encoders. Compared with
traditional open loop stepper systems, a CS-D508 adopted closed loop step system can eliminate potential loss of step,
make real-time position error correction, and do not need torque reservation (100% torque implementation). Also it can
power the driven stepper motor with reduced heating, lower noise, low vibration…
1.1 Features
No loss of step
No torque reservation
No hunting or overshooting
No tuning for easy setup
Capable of powering NEMA 8-34 stepper motors with rotary encoders
Configurable mode for enhanced performance for applications of extra low speed and fast acceleration
Configurable digital output for Fault Output, In Position, or Brake Control
Excellent torque, low noise & vibration, smooth motion
Step & direction or CW/CCW control modes
20-50VDC supply voltage, max 8Aoutput current
Max 200 KHz input frequency
15 micro step settings of 800-51,200 via DIP switches, or 200-51,200 by software
1.2 Applications
When a CS-D508 closed loop stepper drive is implemented with a compatible stepper motor with encoder, the closed
stepper system can be adopted in many small to median speed applications such as CNC routers, CNC mills, CNC
laser cutters, CNC plasma, lab automation instruments, plotters, medical equipment, electronic equipment, small
packaging machines, etc.

2.4 Heat Dissipation
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 and LED Indication
A CS-D508 closed loop stepper drive has 5 connection blocks from P1 to P5 (see figure 2).
Figure 2: CS-D508 connectors
3.1 Connector P1 – Control and Digital Output Connections
3.1.1 Pin Assignments of P1
The P1 connector in Figure 2 are used for connections of input control signals and one configurable digital output.
a) Pinout Definitions
There are 3 control signals for pulse, direction, and enable. See the following table for details.
Pin Name I/O 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). 4.5-24V 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

CS-D508 Closed Loop Stepper Drive User Manual Version 3.1
Page | 5
DIR- I
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.
ENA+ I Enable signal: This signal is used for enabling/disabling the drive. High voltage level of 5-24V
(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 UNCONNECTED & ENABLED.
ENA- I
ALM+ O Configurable Digital Output Signal: A configurable OC output signal. It takes a sinking or
sourcing 20mA current at 5-24V. It can to be configured as one of the 3 types, FAULT
OUTPUT (default), IN POSITION, or BRAKE CONTROL through Leadshine ProTuner CS-D
software.
ALM- O
Notes: (1) Shielding control signal wires is suggested; (2) to avoid/reduce interference, don’t tie control signal cables
and power wires together.
b) Fault Output, In Position, or Brake control Output Configuration
The digital output on the P1 connector, marked as ALM+ & ALM-, is software configurable (read ProTuner CS-D
software manual). It can be configured as one of the available 3 options – “Fault Output”, “In Position”, and “Brake
Control”. Those 3 options are described as below:
•Fault Output
The FAULT output is the default configuration. It signals a fault condition of CS-D508, including over-voltage,
over-current, or position following error. This output can be used to drive devices such as a relay, a LED, etc.; or as
an input signal for a PLC or I/O devices.
For example, for a multi-axis CNC machine, when one of the axes fails, such a fault output signal can be sent to
the motion controller of the machine and trigger an automatic machine shutdown.
•In Position
Use Leadshine ProTuner for CS-D software to configure this output as an IN POSITION output. In this case a
digital output signal will be sent out, when the targeted position is in the “Target Range” (refer to parameter
Distance to Send "In position" Output Signal in software manual).
•Brake Control
Use Leadshine ProTuner for CS-D software to configure this output as a BRAKE CONTROL output. In this case,
this signal can be used for automatic brake control while system power failure.
