Elimination of Heat
Driver’s reliable working temperature should be <70℃(158 ℉), and motor working
temperature should be <80℃(176℉);
It is recommended to use automatic idle-current mode, namely current automatically reduce
to 50% when motor stops, so as to reduce driver heating and motor heating;
It is recommended to mount the driver vertically to maximize heat sink area. Use forced
cooling method to cool the system if necessary.

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).

Selecting Active Pulse Edge and Control Signal Mode
The 3DM580 supports PUL/DIR and CW/CCW modes and pulse actives at rising or falling edge.
See more information about these settings in Section 13. Default setting is PUL/DIR mode and
rising edge active (NPN, and PNP control signal is on the contrary).

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.

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
