Description
Introduction
Cloudray DM556 5.6A Stepper Motor Driver is a professional 4-wire, 6-wire or 8-wire two-phase stepper motor driver Nema 17, Nema 23, Nema 24 or Nema 34 with phase current less than 5.6 A. Drive voltage is from 18VDC to 50VDC.
Cloudray DM556 stepper motor driver and its key features:
- Anti-resonance, ensures optimal torque and minimizes the instability of the middle area
- Self-testing and auto-configuration technology enables optimal performance of various engines
- Microstep resolution
- Protection against overvoltage and overcurrent
- DC power supply 18-50 VDC (36 VDC recommended)
- Maximum drive current 5.6 A
- The idle current can be set to half
- 16 selectable micro step resolutions from 200 to 25600
- Input pulse frequency up to 200 KHz
Data sheet
Signal interface details:
The controller and stepper motor driver can be connected in two ways. At the common cathode connection, a high electrical level is active; all control negative signals are connected to GND. A low electrical level is active at the common anode connection; all positive control signals are connected to 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 (≥1/4 W) |
| 24V | 2kΩ (≥1/2 W) |
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. |
