Description
Introduction
DM556 digital stepper motor driver is developed with DSP control algorithm. Compared to analog or TB6600H drivers, it can drive a stepper motor at much lower noise, lower temperature and smoother motion. It is suitable for 4-wire, 6-wire or 8-wire two-phase stepper motor Nema 23, Nema 34 and phase current less than 5.6 A. Drive voltage is from 20VDC to 50VDC.
The driver is intended for use in a non-industrial environment. Recommended for use in an industrial environment Leadshine DM556.
DM556 digital stepper motor driver and its key features:
- Protection against overvoltage and overcurrent
- DC power supply 20-50 VDC (36 VDC recommended)
- Maximum drive current 5.6 A
- You can set the standby current to half
- 15 selectable micro step resolutions from 400 to 25600
- Input pulse frequency up to 200 KHz, TTL compatible and optically isolated input

Signal interface details:
The controller's control signals can be active at high or low electrical levels. When the high electrical level is active (common cathode connection), all control negative signals are connected to GND. When the low electrical level is active (common anode connection), all positive control signals are connected to a positive voltage. See the images below for details:
- Common cathode connection
- Common anode connection
You can use a 5 – 24 V controller signal, but make sure the appropriate resistor is used:
| Amplitude of the signal | External limiting resistor R (see figure above) |
|---|---|
| 5V | Without R. |
| 12V | 1kΩ |
| 24V | 2kΩ |
Motor and power supply interface details:
| Motor terminals | A+ | 4 motor wires must be connected. In most cases, these wires are color coded. The color associated with the winding depends on the motor. See engine documentation for details. |
