3. Pin Assignment and Description
The 3DM580 has two connectors, connector P1 for control signals connections, and connector P2
for power and motor connections. The following tables are brief descriptions of the two connectors.
More detailed descriptions of the pins and related issues are presented in section 4, 5, 9.
Connector P1 Configurations
Pin Function
Details
PUL+
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse
signal, each rising or falling edge active; 4-5V when PUL-HIGH, 0-0.5V when
PUL-LOW. In double pulse mode (pulse/pulse) , this input represents
clockwise (CW) pulse ，active both at high level and low level. For reliable
response, pulse width should be longer than 2.5μs. Series connect resistors for
current-limiting when +12V or +24V used. The same as DIR and ENA signals.
PUL-
DIR+
DIR signal: In single-pulse mode, this signal has low/high voltage levels,
representing two directions of motor rotation; in double-pulse mode, this signal
is counter-clock (CCW) pulse ，active both at high level and low level. For
reliable motion response, DIR signal should be ahead of PUL signal by 5μs at
least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that
rotation direction is also related to motor-driver wiring match. Exchanging the
connection of two wires for a coil to the driver will reverse motion direction.
DIR-
ENA+
Enable signal: This signal is used for enabling/disabling the driver. High level
(NPN control signal, PNP and Differential control signals are on the contrary,
namely Low level for enabling.) for enabling the driver and low level for
disabling the driver. Usually left UNCONNECTED (ENABLED).

4. Control Signal Connector (P1) Interface
The 3DM580 can accept differential and single-ended inputs (including open-collector and PNP
output). The 3DM580 has 3 optically isolated logic inputs which are located on connector P1 to
accept line driver control signals. These inputs are isolated to minimize or eliminate electrical
noises coupled onto the drive control signals. Recommend use line driver control signals to
increase noise immunity of the driver in interference environments. In the following figures,
connections to open-collector and PNP signals are illustrated.

Figure 3: Connection to PNP signal (common-cathode)
5. Connecting the Motor
The 3DM580 can drive any 3 lead or 6 lead three phase hybrid stepping motors. The connection
between the driver and 3-phase stepping motors includes two different kinds of connections,
namely delta-connection and star-connection. Using delta-connection, the performances of the
motor under high speed condition are better, but the driver current is higher too (about 1.73 times
the motor coil current); while using star-connection, the driver current equals to the motor coil
current.
Figure 4: Motor connections
6. Power Supply Selection
The 3DM580 can match medium and small size stepping motors (from NEMA frame size 14 to 34)
made by Leadshine or other motor manufactures around the world. To achieve good driving
performances, it is important to select supply voltage and output current properly. 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

3DM580 Digital Stepping Driver Manual V1.1
Tel: [phone] Web Site: www.leadshine.com
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 reliability.
Regulated or Unregulated Power Supply
Both regulated and unregulated power supplies can be used to supply the driver. However,
unregulated power supplies are preferred due to their ability to withstand current surge. If
regulated power supplies (such as most switching supplies.) are indeed used, it is important to
have large current output rating to avoid problems like current clamp, for example using 4A
supply for 3A motor-driver operation. 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 driver 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.
Multiple Drivers
It is recommended to have multiple drivers to share one power supply to reduce cost, if the supply
has enough capacity. To avoid cross interference, DO NOT daisy-chain the power supply input
pins of the drivers. Instead, please connect them to power supply separately.
Selecting Supply Voltage
The power MOSFETS inside the 3DM580 can actually operate within +20 ~ +50VDC, including
power input fluctuation and back EMF voltage generated by motor coils during motor shaft
deceleration. 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 driver damage. Therefore, it is suggested to
choose only sufficiently high supply voltage for intended applications, and it is suggested to use
power supplies with theoretical output voltage of +20 ~ +45VDC, leaving room for power
fluctuation and back-EMF.
7. Selecting Microstep Resolution and Driver Output Current
Microstep resolutions and output current are programmable, the former can be set from 200 to

3DM580 Digital Stepping Driver Manual V1.1
Tel: [phone] Web Site: www.leadshine.com
51,200 steps/rev and the latter can be set from 1.0A to 8.0A. See more information about
Microstep Resolution and Output Current Setting in Section table.
However, when it’s not in configured mode, this driver uses an 8-bit DIP switch to set microstep
resolution, and motor operating current, as shown below:

For a given motor, higher driver current will make the motor to output more torque, but at the
same time causes more heating in the motor and driver. Therefore, output current is generally set
to be such that the motor will not overheat for long time operation. Since parallel and serial
connections of motor coils will significantly change resulting inductance and resistance, it is
therefore important to set driver output current depending on motor phase current, motor leads and
connection methods. Phase current rating supplied by motor manufacturer is important in selecting
driver current, however the selection also depends on leads and connections. Select a setting
closest to your motor’s required current.
Notes: Due to motor inductance, the actual current in the coil may be smaller than the dynamic
current setting, particularly under high speed condition.
Microstep Resolution
When it’s not in configured mode, the LAST three bits (SW6, 7, 8) of the DIP switch are used to
set the microstep resolution..

Standstill current setting
SW5 is used for this purpose. OFF meaning that the standstill current is set to be half of the
selected dynamic current, and ON meaning that standstill current is set to be the same as the
selected dynamic current.

The current automatically reduced to 50% of the selected dynamic current one second after the last
pulse. Theoretically, this will reduce motor heating to 25% (due to P=I2*R) of the original value. If
the application needs a different standstill current, please contact Leadshine.
8. Wiring Notes
In order to improve anti-interference performance of the driver, it is recommended to use
twisted pair shield cable.
To prevent noise incurred in PUL/DIR signal, pulse/direction signal wires and motor wires
should not be tied up together. It is better to separate them by at least 10 cm, otherwise the
disturbing signals generated by motor will easily disturb pulse direction signals, causing
motor position error, system instability and other failures.
If a power supply serves several drivers, separately connecting the drivers is recommended
instead of daisy-chaining.
It is prohibited to pull and plug connector P2 while the driver is powered ON, because there
is high current flowing through motor coils (even when motor is at standstill). Pulling or
plugging connector P2 with power on will cause extremely high back-EMF voltage surge,
which may damage the driver.
9. Typical Connection
A complete stepping system should include stepping motor, stepping driver, power supply and
controller (pulse generator). A typical connection is shown as figure 9.

10. Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some
rules, shown as following diagram:
Figure 10: Sequence chart of control signals
Remark:
a) t1: ENA must be ahead of DIR by at least 5s. Usually, ENA+ and ENA- are NC (not
connected). See “Connector P1 Configurations” for more information.
b) t2: DIR must be ahead of PUL active edge by 5s to ensure correct direction;
c) t3: Pulse width not less than 2.5s;
d) t4: Low level width not less than 2.5s.
11. Protection Functions
To improve reliability, the driver incorporates some built-in protection functions. The 3DM580
uses one RED LED to indicate what protection has been activated. The periodic time of RED is
3 s (seconds), and how many times the RED turns on indicates what protection has been
activated. Because only one protection can be displayed by RED LED, so the driver will decide
what error to display according to their priorities. See the following Protection Indications
table for displaying priorities.
Over-current Protection
Over-current protection will be activated when continuous current exceeds the upper limit or in
case of short circuit between motor coils or between motor coil and ground, and RED LED will
turn on once within each periodic time (3 s).

3DM580 Digital Stepping Driver Manual V1.1
Tel: [phone] 11 Web Site: www.leadshine.com
Over-voltage Protection
When power supply voltage exceeds 62±1 VDC, protection will be activated and RED LED will
turn on twice within each periodic time (3 s).
Short-Circuit Protection
Motor power lines wrong & not connected will activate this protection. RED LED will turn on
four times within each periodic time (3 s).
Attention: When above protections are active, the motor shaft will be free or the LED will turn
red. Reset the driver by repowering it to make it function properly after removing above problems.
Since there is no protection against power leads (﹢,﹣) reversal, it is critical to make sure that
power supply leads correctly connected to driver. Otherwise, the driver will be damaged instantly.

12. Frequently Asked Questions
In the event that your driver 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.
