DM556 Digital Stepper Motor Driver
Product Information: MotorDriver DM556
The MotorDriver DM556 is a digital stepper drive that is
designed for easy setup and simple operation. The stepper drive
uses advanced stepper control technology to power 2-phase and
4-phase stepper motors smoothly with optimal torque and low motor
heating & noise. It has an operating voltage of 20-50VDC and
can output up to 5.6A current. The microstep and output electrical
current configuration can be done via DIP switches. This stepper
drive is an ideal choice for applications requiring simple step
& direction control of NEMA 23, 24 and 34 stepper motors.
Features and Specifications:
- Control signals connector
- Pulse (STEP) signal: Pulse inputs active at rising edge; 4-5V
when PUL-HIGH, 0-0.5V when PUL-LOW. Minimal pulse width of 2.5s.
Add a resistor for current-limiting at +12V or +24V input logic
voltage (1K for +12V, 2k for +24V; The same is for DIR and ENA
signals). - DIR (DIRECTION) signal: This signal has low/high voltage levels
to represent two directions of motor rotation.. Minimal direction
setup time of 5s. Also swapping the connection of two wires of a
coil (e.g. A+ and A-) to the drive will reverse motor
direction. - Enable signal: This signal is used for enabling/disabling the
drive. High level +5V for enabling the drive and low level for
disabling the drive. By default it is left UNCONNECTED
(ENABLED).
- Pulse (STEP) signal: Pulse inputs active at rising edge; 4-5V
- DIP switch
- Microstep Resolution Configurations: SW5
- Current Configurations: Peak Current ON/OFF SW1, SW2, SW3
- Motor idle current configurations: SW4
- Protection Functions
- Two LED lights on the driver: GREEN (power indicator) and RED
(protection indicator) - Protection types: Over-current protection, Over-voltage
protection
- Two LED lights on the driver: GREEN (power indicator) and RED
Product Usage Instructions:
To use the MotorDriver DM556, follow these steps:
- Connect the control signals connector to the stepper
motor. - Configure the microstep and output electrical current using the
DIP switches. - Set the motor idle current percentage using SW4.
- Configure the peak current using SW1, SW2, and SW3.
- Apply power to the stepper drive.
- Send pulse (STEP) signals to the stepper drive to rotate the
motor in the desired direction. - If needed, use DIR (DIRECTION) signal to change the direction
of motor rotation. - Use the Enable signal to enable/disable the stepper drive.
- Observe the GREEN power indicator which should be always
on. - Observe the RED protection indicator which will flash 1-2 times
in a 3-second period if protection is enabled. Different number of
flashes indicates different protection type.

Enable signal: This signal is used for enabling/disabling the drive. High level +5V for enabling the drive and low level for disabling the drive. By default it is left UNCONNECTED (ENABLED).
DIP switch
· Drive uses an 8-bit DIP switch to set micro-step resolution and motor operating current · Microstep resolution is set by SW 5, 6, 7, 8 of the DIP switches · Operating electrical current is set by SW 1, 2, 3 of the DIP switches · Motor idle current percentage is set by SW 4 of the DIP switches

Motor idle current configurations:
SW4 is used to set motor idle current percentage. At OFF position it means the standstill current is set to be 50%of the selected output current.
At ON position it means standstill current is set to be the same as the selected dynamic current. The current automatically reduced to 50% of the selected dynamic current 0.4 second after the last pulse.
Protection Functions
There are two LED lights on the driver.
-The GREEN one is the power indicator which will be always on generally. -The RED one is a protection indicator which will flash 1-2 times in a 3-second period, when protection is enabled.
Different number of flashes indicates different protection type.

Power and motor connector:
Power connector:
Driver 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 range of +24 – +48 VDC, 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.
Motor Connector:
Driver can drive 2-phase and 4-phase bipolar hybrid stepper motors with 4, 6, or 8 wires.
