The DM556 is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with analog or TB6600H chips driver, it can drive a stepper motor at much lower noise, lower heating, and smoother movement. It is suitable for 4 wire, 6 wire or 8 wires two-phase hybrid stepper motor with 42mm to 86mm outside diameter and less than 5.6A phase current. The drive voltage of which is from 20VDC to 50VDC. It is widely used in middle and big size numerical control devices such as curving machine, CNC machine, computer embroider machine, packing machines and so on.

Key Features:

  • Strong anti-interference ability, high precision positioning can be achieved in the harsh environment of the power grid
  • Over-voltage and over-current protections
  • DC Power supply 20-50 VDC (36 VDC is recommended)
  • Maximum drive current 5.6 A
  • Standby current can be set to half
  • 15 selectable microstep resolutions from 400 to 25600
  • Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input

Signal interface details:

Controller’s control signals can be active in high or low electrical level. When the high electrical level is active (common cathode connection), all control negative signals will be connected together to GND. When the low electrical level is active (common anode connection), all control positive signals will be connected together to public port. See below pictures for details:

  • Common cathode connection

  • Common anode connection

You can use 5 – 24 V signal of a controller, just make sure that the appropriate resistor is used:

Signal amplitude External current limiting resistor R
5V Without R
12V 1kΩ
24V 2kΩ

Motor and power supply interface details:

Motor pins A+ 4 wires of a motor must be connected. In most situations those wires are color coded. Color associated with a winding depends on the motor. Please refer to the motor’s documentation for details.
Power supply pins DC+ Power supply: 20-50 VDC
