3 Pin Assignment and Description
The 3M583 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
3
ECG--SAVEBASE
3M583 Microstepping Driver Manual V1.0
connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5,
9.
3.1 Connector P1 Configurations
Pin Function
Details
PUL+
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, effective
for each rising edge; 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode
PUL-
(pulse/pulse) , this input represents clockwise (CW) pulse,effective for high level. For reliable
response, pulse width should be longer than 1.2μs. Series connect resistors for current-limiting
when +12V or +24V used.
DIR+
Representing two directions of motor rotation; in double-pulse mode(set by inside jumper), this
signal is counter-clock (CCW) pulse, effective for high 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-
DIR-LOW. Please note that motion 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.
ENA+
(NPN control signal, PNP and Differential control signals are on the contrary, namely Low level
ENA-
for enabling.) for enabling the driver and low level for disabling the driver. Usually left
UNCONNECTED (ENABLED).
Notes: PUL/DIR mode is the default mode, and under-cover jumper J1 can be used to switch it to
CW/CCW mode.
Selecting CW/CCW or PUL/DIR Mode
There is a jumper J1 (including pin 1 to pin 9) inside the 3M583 specifically for selecting pulse
signal mode. Settings for the one-pulse mode (PUL/DIR) and for the double-pulse mode
(CW/CCW) are shown in the following figure. Default mode out of factory is PUL/DIR mode and
effective at rising edge.

4 Connections to Controller
The 3M583 can accept differential and single-ended control signals (including open-collector,
namely common-anode and PNP output, namely common-cathode). The 3M583 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 control signals. It is
recommended to use line driver control signals to increase noise immunity of the driver under an
interference environment. Connections to open-collector and PNP signals are illustrated in the
figure.

5 Connections to 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
6
ECG--SAVEBASE
3M583 Microstepping Driver Manual V1.0
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 5-1 Motor connections
6 Power Supply Selection
The 3M583 can match medium and small size stepping motors (from NEMA size 17 to 34) made
by 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 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 is
better to use lower supply voltage to decrease noise, heating and improve reliability.
6.1 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
7
3M583 Microstepping Driver Manual V1.0
ECG--SAVEBASE
rating.
6.2 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.)
6.3 Selecting Supply Voltage
The power MOSFETS inside the 3M583 can actually operate within +18~50VDC, 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 +24~+ 45V, leaving room for power fluctuation
and back-EMF.
7 Microstep Resolution and Output Current Settings
The 3M583 uses an 8-bit DIP switch to set motor dynamic current, standstill current and
microstep resolution, as shown below:
7.1 Microstep Resolution Selection
Microstep resolution is set by SW6, 7 and 8 of the DIP switch as shown in the following table:

7.2 Current Settings
For a given motor, higher driver current will make the motor 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. Phase current rating supplied by
motor manufacturer is important in selecting driver current, however the selection also depends on
leads and connections.
7.2.1 Dynamic Current Setting
The first four bits (SW1, 2, 3, 4) of the DIP switch are used to set the dynamic current. 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.
7.2.2 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 60% of the selected dynamic
current 0.5 second after the last pulse when use automatic idle-current reduction mode.
Theoretically, this will reduce motor heating to 36% (due to P=I2*R) of the original value.
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.

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:

Remark:
(1) t1: ENA must be ahead of DIR by at least 5μs. Usually, ENA+ and ENA- are NC (not
connected). See “Connector P1 Configurations” for more information.
(2) t2: DIR must be ahead of PUL effective edge by at least 5μs to ensure correct direction;
(3) t3: Pulse width not less than 1.5μs;
(4) t4: Low level width not less than 1.5μs.
11 Protection Functions
To improve reliability, the driver incorporates some built-in protections features.
Short-voltage and Over-voltage protection
When power supply voltage exceeds +51VDC, protection will be activated and power indicator
LED will turn red. When over-voltage protection function is active, the user should repower the
driver to reset the driver.
When power supply voltage is lower than +18VDC, the Green LED will turn off and the Red LED
will light. Both green and red LED will turn off when power supply voltage is lower than
+16VDC.The driver will be reset after power supply voltage increase to +20VDC automatically.
Over-current Protection
Protection will be activated in case of over current which may otherwise damage the driver.
Attention: Since there is no protection against power leads (+, -) reversal, it is critical to make
sure that power supply leads correctly connected to the driver. Otherwise, the driver will be
damaged instantly.
Note: When above protections are active, the motor shaft will be free and the RED ALARM LED
will light. Reset the driver by repowering it to make it function properly after removing above
problems.

12 Frequently Asked Questions
In the event that your driver does not 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. Many of the problems that affect motion
control systems can be traced to electrical noise, controller software errors, or mistake in wiring.
