Technical Specifications Quick-View

Key Features

• Active Cooling Fan: The "H" in DM860H signifies a built-in heavy-duty heatsink paired with an automatic cooling fan. It prevents thermal throttling during prolonged industrial operations. 
• 32-Bit DSP Technology: Uses digital signal processing to compute pure-sinusoidal current control. This drastically minimizes motor resonance, eliminates mid-range instability, and offers double the speed performance of older analog chips. 
• Automatic Idle-Current Reduction: Automatically drops the coil current by 50% roughly one second after the motor stops moving. This keeps both the motor and the driver running cool while at a standstill. 
• Hardware Protections: Features built-in auto-shutdown protocols for over-voltage, under-voltage, over-current, and short-circuits.

Port & Wiring Configurations

• Power Terminals:
  • AC / DC+ and AC / GND: Flexible power inputs. Unlike basic drivers, you can wire it directly to an AC transformer output (up to 80VAC) or a DC switching power supply (up to 110VDC).
• Motor Terminals:
  • A+ / A- and B+ / B-: Connects directly to the two phases of your stepper motor. 
• Control Signal Terminals:
  • PUL+ / PUL-: Pulse input controlling motor speed and steps.
  • DIR+ / DIR-: Direction signal controlling clockwise or counter-clockwise rotation.
  • ENA+ / ENA-: Enable/Disable toggle (can generally be left disconnected/floating if you want the motor permanently locked when powered).
