1. Introd uction

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…

3. Connections an d L ED Indi cat i on

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 Connect ions

3.1.1 Pin Assignm ent s 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.

PUL- I

(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.

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

Page | 4

DIR- I

drive. PNP and Differential control signals are on the contrary, namely Low level for enabling.

CS-D508 Closed Loop Stepper Drive User Manual Version 3.1

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 enabli ng the dr iv e and l ow vol tage lev el of 0-0.5VDC for disabling the

ENA- I

By default this signal is left UNCONNECTED & ENABLED.

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

ALM- O

software.

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.

3.6 LED Light Indication

There are two LED lights for CS-D508, one red and one green. The GREEN one is the power indicator which will be
always on generally. The RED one is a protection indicator. It is off always when a CS-D508 operates normally, but
will flash 1, 2 or 7 times in a 5-second period when error protection is enabled. Different number of flashes indicates
different protection type (read Section 9).

4. Motor Selection

The CS-D508 is designed to power 2-phase (or 4-phase 0.9 degree) NEMA 17/23/24 stepper motors under 10000-line
incremental encoders (recommend 1000-line). Leadshine offers many high performance stepper motors compatible
with the CS-D508 which you can find in the Appendix A of this document. The CS-D508 can also power similar
stepper motors with incremental encoders from third-party suppliers.

5. Power Supply Selection

The CS-D508 can power small and medium size closed loop stepper motors (frame size from NEMA17 to 24) from
Leadshine (see Appendix A) or other motor manufacturers. To get good system performance, it is important to select
proper supply voltage and output current. Generally speaking, supply voltage determines the high speed performance
of the motor, while output current determines the output torque of the driven motor (particularly at lower speed).
Higher supply voltage will allow higher motor speed to be achieved, at the price of more noise and heating. If the
motion speed requirement is low, it’s better to use lower supply voltage to decrease noise, heating and improve

Page | 8

CS-D508 Closed Loop Stepper Drive User Manual Version 3.1

reliability.

Notes: See Appendix B at the end of this document for Leadshine CS-D508 compatible switching power supplies
specially designed for stepper & servo controls.

5.1 Regulated or Unregulat ed Power Sup ply

Both regulated and unregulated power supplies can be used to supply the drive. However, unregulated power supplies
are preferred due to their ability to withstand current surge and fast response for current change. If you prefer to a
regulated power supply, it is suggested to choose such a power supply specially designed for stepper/servo controls
such as Leadshine RPS series (http://www.leadshine.com/producttypes.aspx?producttype=regulated-switching

). Or, in
the case when only normal switching power supplies are available, it is important to use “OVERSIZE” high current
output rating power supplies (for example, using a 4A power supply for 3A stepper motor) to avoid problems such as
current clamp. On the other hand, if unregulated supply is used, one may use a power supply of lower current rating
than that of motor (typically 50%-70% of motor current). The reason is that the drive draws current from the power
supply capacitor of the unregulated supply only during the ON duration of the PWM cycle, but not during the OFF
duration. Therefore, the average current withdrawn from power supply is considerably less than motor current. For
example, two 3A motors can be well supplied by one power supply of 4A rating.

5.2 Power Supply Sharing

Multiple CS-D508 drives can share one power supply to save space and reduce cost, if that power supply has enough
power capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply separately.
To avoid cross interference, DO NOT daisy-chain connect the power supply input pins of the Drivers. Instead connect
them to power supply separately.

5.3 Selecting Supply Voltage

The CS-D508 is designed to operate within 20-50VDC voltage input. When selecting a power supply, besides voltage
from the power supply power line voltage fluctuation and back EMF voltage generated during motor deceleration
needs also to be taken into account. Ideally it is suggested to use a power supply with the output of 20-48VDC, leaving
room for power line voltage fluctuation and back-EMF.

Higher supply voltage can increase motor torque at higher speeds, thus helpful for avoiding losing steps. However,
higher voltage may cause bigger motor vibration at lower speed, and it may also cause over-voltage protection or even
drive damage. Therefore, it is suggested to choose only sufficiently high supply voltage for intended applications.

6. DIP Switch Configurat ions

The CS-D508 has a built-in 8-bit DIP switch to set microstep resolution, motor direction, auto-tuning switch and so on.

10. Software Confi guration

The CS-D508 is designed for simple setup and implementation. For most applications no software configuration or
tuning is needed especially when driving Leadshine stepper motors with encoders (see Appendix A). If you want to do
fine tuning or custom configurations such as micro-step, current percentage change…, you can use Leadshine’s free
ProTuner software to make the changes.

12. Troubleshoot ing

In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or
mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this
process you may have to disconnect the individual components that make up your system and verify that they operate
independently. It is important to document each step in the troubleshooting process. You may need this documentation
to refer back to at a later date, and these details will greatly assist our Technical Support staff in determining the
problem should you need assistance.

Many of the problems that affect motion control systems can be traced to electrical noise, controller software errors, or
mistake in wiring.

CS-D508 Closed Loop Stepper Drive User Manual Version 3.1

Appendix C. Powering a Third Party Motor with CS-D508

To get the best system performance and most convenience for setup, it is highly recommended to choose a Leadshine
closed stepper motor along with the CS-D508 closed loop stepper drive. See Appendix A for frequently used Leadshine
closed loop stepper motors. If you can’t find one meeting your requirements there, contact Leadshine sales by
emailing [email protected] or [email protected]
one already there which can satisfy your application need already.

In the case of powering a third party closed loop stepper motor, pay special attention as described below.

• Your stepper motor must be a 2-phase stepper motor

• Your stepper motor must be mounted with a quadrature rotary encoder with the resolution of 500-5,000 line

(2,000- 20,000 counts).

• When the CS-D508 is first-time powered on after your stepper motor is connected, check the following

possible causes if a position following error (see Section 9 above).

o Confirm both encoder and power cables are connected properly and tightly secured.
o Power off the drive then swap the A+ and A- motor connections to the CS-D508 drive. The reason is

the definitions of your Motor A+ and A- are different from those marked on CS-D508 motor
connection pins (P3 of Figure 2).

. Leadshine offers many other custom models. There may be

If protection error is still seen after the above steps, contact your CS-D508 drive or Leadshine technical
support.
