signal. A pulse signal is active at the rising or falling voltage edge (set by DIP switch SW13).
(2). In double-pulse (CW/CCW) control mode (set by DIP switch SW14), this signal input
represents clockwise (CW) pulse, and is active at both high voltage level and low voltage
level. (3). 3.5-5V for voltage HIGH, 0-0.5V for voltage LOW (same for DIR signals).
(4). Pulse width should be set to 1μs or longer. (5). Series connect resistors 1KΩ or 2KΩ
for current-limiting when +12V or +24V respectively. The same as DIR and ENA signals.
Direction signal: (1). In single pulse (step & direction) control mode, this signal’s low andhigh voltage levels represent the two directions of motor rotation (e.g. clockwise andcounterclockwise). (2). In double-pulse (CW & CCW) control mode, this signal representscounterclockwise (CCW) rotation. It is active at both voltage high level and low level. (3).
Minimal DIR signal setup time should be at least 5μs.
Enable signal: (1). This signal is used for enabling/disabling the drive. High voltage level of
3.5-5VDC (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.(2). ENA signal requires advance DIR signal minimum 500ms in single
pulse mode. (3). By default this signal is left UNCONNECTED & ENABLED.

4. Control Signal and Fault Output Wiring
4.1 Control Signal Connection
The 3DM580S can accept differential and single-ended control signal inputs (open-collector and PNP output). A 3DM580S has 3
optically isolated control inputs, PUL, DIR, and ENA. Refer to the following two figures for connections of open-collector and
PNP signals.

4.2 Fault Output Connection
When over voltage or over current protection happens, 3DM580S red status LED light will blink and the impedance state
between ALM+ and ALM- will change (from low to high or high to low depending on configuration) and can thus be detected.
Fault output connection is optional, and it can be connected either in sinking or sourcing.

3DM580S 3-Phase Digital Stepper Drive User Manual

Figure 5

Fault output connections

4.3 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 6 Sequence chart of control signals

Remark:(1) t1: ENA must be ahead of DIR by at least 500ms. Usually, ENA+ and ENA- are NC (no connected).
(2) t2: DIR must be ahead of PUL effective edge by 5us to ensure correct direction.
(3) t3: Pulse width not less than 1us, these widths are based on a 50% duty cycle. If it is greater or less than 50%, thewidth time is required to be wider.
4.4 Typical Connection

In order to improve anti-interference performance of the Drive, 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.

3DM580S 3-Phase Digital Stepper Drive User Manual

If a power supply serves several Drives, separately connecting the Drives is recommended instead of daisy-chaining.



It is prohibited to pull and plug connector P3 while the drive is powered ON, because there is high current flowing throughmotor coils (even when motor is at standstill). Pulling or plugging connector P3 with power on will cause extremely highback-EMF voltage surge, which may damage the Drive.



It is strictly prohibited to add tin to the wire head to access the terminal, otherwise the contact resistance may become large
and overheating damage to the terminal.
The wire head should not be exposed outside the terminal to prevent accidental short circuit and damage to the drive.



5. DIP Switch Configurations
The 3DM580S has two 8-bit DIP switches. “Default” means that parameters can be modified by Leadshine PC software
software.The first 8-bit is located on the side (DIP switch selector 1 in Figure 2) and used to configure settings of micro step
resolution, output current, and motor standstill current as shown below,

5.1 Output Current (SW1-SW4)
The 3DM580S has 8 output current settings which can be configured through DIP switch SW1, SW2, SW3 and SW4.
For a given stepper motor, as normal setting the output current to 1.4 times of motor phase current, will make it output larger
torque, but at the same time cause more heating for both the motor and drive. Therefore, it is suggested to set a output current(peak of sinusoidal) to no more than 1.2 times the stepper motor’s (for 4-lead motor) phase current to prevent overheating .
The SW1, SW2 and SW3 are used to set the dynamic current. Select a setting closest to your motor’s required current. Whenthey are set to OFF, OFF, OFF, OFF, the output current can be set by Leadshine PC software.

5.2 Standstill Current Setting (SW5)The SW5 of an 3DM580S is used to set output current percentage when motor is standstill. Idle current percentage will be set to50% at OFF position, and 90% at ON position. When the driven stepper motor is idle (no movement) for 0.4 second, the output
current of 3DM580S will be automatically reduced to the configured percentage.
5.3 Microstep Resolution (SW6-SW8)
Each 3DM580S has 8 micro step settings which can be configured through DIP switch SW6, SW7 and SW8. The driver has aninternal calculator to achieve 200 steps to make the 3-phase stepper motor turn one turn. See the following table for detail. Whenthey are set to ON, ON, ON, the microstep can be set via Leadshine PC software.

5.4 Smoothing Filter Table (SW9-SW10)
3DM580S has an advanced feature called control command smoothing to make the input pulse from pulse generator (controller,
PLC, etc.) S-curve acceleration, to improve motion smoothness and high-speed start frequency in many circumstances. This isachieved through adding filtering time which is configured SW9-SW10. See the following table for how to configure.

5.5 Motion Mode Configuration (SW11)

SW11=off: Low Speed Smooth Mode, suitable for applications requiring high smoothness at low speeds.
SW11=on: Large Torque Mode, suitable for applications requiring high output torque for high speeds.
5.6 Alarm Output Configuration (SW12)
DIP switch SW12 is used to configure the impedance state of alarm output (fault output).
When SW12 is set to OFF (factory setting) the resistance between ALM and COM- is set to low impedance in normal operation,
and will change to high impedance when the drive goes into fault.
When SW12 is set to ON position, that resistance will be set to high impedance in normal condition and changed to low
impedance under error protections.
Note: Alarm output resistance setting according to customer's actual requirements
5.7 Activated Pulse Edge Configuration (SW13)
DIP switch SW13 is used to configure activated pulse edge.
Setting it to OFF position (factory setting) means that a pulse is activated at voltage falling edge,.
Setting it to ON position means a pulse is activated at rising edge. Make sure this setting will match the pulse generator(controller, PLC, etc.).
5.8 Pulse Mode Configuration (SW14)
DIP switch SW14 is used to configure the pulse mode.
Setting to OFF (Factory setting) is single pulse (step & direction, or pulse &direction) control.
Setting to ON to change the control model to double pulse (CW/CCW) control type.
5.9 Shaft Lock in Non-enabled State (SW15)
SW15=off: when the Drive is non-enabled, it does not respond to pulses, there is no current output, and the motor is not locked(factory setting).
SW15=on: When the Drive is not enabled, it does not respond to pulse, there is current output, and the motor is locked.
5.10 Self-Test Configuration (SW16)
SW16=off: self-test disabled (factory default).
SW16=on: self-test enabled, the motor turns forward one revolution and then reverses one revolution at 0.2R/S

6. Power Supply Selection
The 3DM580S can power small and medium size 3-phase stepper motors (frame size from NEMA17 to 34) from Leadshine orother 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 theoutput torque of the driven motor (particularly at lower speed). Higher supply voltage will allow higher motor speed to beachieved, at the price of more noise and heating. If the motion speed requirement is low, it’s better to use lower supply voltage todecrease noise, heating and improve reliability.

3DM580S 3-Phase Digital Stepper Drive User Manual

6.1 Regulated or Unregulated Power Supply
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 LSP series .
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 frompower supply is considerably less than motor current. For example, two 3A motors can be well supplied by one power supply of
4A rating.
6.2 Power Supply Sharing
Multiple 3DM580S 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 crossinterference, DO NOT daisy-chain connect the power supply input pins of the Drivers. Instead connect them to power supply
separately.
6.3 Selecting Supply Voltage
The 3DM580S is designed to operate under 74VDC voltage input. When selecting a power supply, besides voltage from thepower 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.

3DM580S 3-Phase Digital Stepper Drive User Manual

7. Motor Selection
The 3DM580S can be used to drive 3- or 6-wire three-phase hybrid stepper motors with a step angle of 1.2 degrees. The choiceof motor is mainly determined by the motor torque and current rating. The torque size is mainly determined by the size of the
motor. The larger the size of the motor, the higher the torque of the motor; while the current size is mainly related to the
inductance, the motor with small inductance has good performance in high speed performance, but the current is higher.

8. Troubleshooting
In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical innature. 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 todocument each step in the troubleshooting process. You may need this documentation to refer back to at a later date, and thesedetails 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 mistakein wiring.
