Quick Deployment Guide
Core Specifications Reference
Component Key Parameters Compatibility Notes
DM860C Driver DC20-110V AC 18-80V power, 2.4-7.2A current, 16 micro-step settings Current adjustable to match 86CM45, DIP switch configuration
86CM45 Stepper Motor NEMA34, 4.5N·m torque, 6A current Connect windings to A+/A- and B+/B- terminals
Wiring Specifications
Power Supply Wiring:
  • DC+ → Positive pole of 48-70VDC power supply (≥500W recommended)
  • DC- → Negative pole of power supply
Essential: Connect 1000μF/50V capacitor at power terminal and ground the housing for interference protection.
Motor Wiring:
Driver Terminal Motor Connection Notes
A+ Motor Winding A Positive (red) Connect windings in pairs; do not mix A/B groups
A- Motor Winding A Negative (black) Reverse connection affects rotation direction
B+ Motor Winding B Positive (green)
B- Motor Winding B Negative (blue)
Control Signal Wiring:
  • PUL+ → Pulse signal positive
  • PUL- → Pulse signal negative (signal ground)
  • DIR+ → Direction signal positive
  • DIR- → Direction signal negative
Important: Do not route control signals parallel to power wires; maintain minimum 10cm separation.
DM860C DIP Switch Settings
Function Switch Position Setting Value Notes
Current Adjustment (SW1-SW4) SW1=ON, SW2=ON, SW3=OFF, SW4=OFF 6.0A Matches 86CM45 rated current
Micro-Stepping (SW5-SW8) SW5=ON, SW6=OFF, SW7=OFF, SW8=OFF 1600 Pulses/Revolution Optimal for medium-high precision applications
DIP switch adjustments must be performed with power disconnected. Settings activate upon driver restart.
Commissioning Procedure
  • Step 1: Power-off verification - Check all connections and DIP switch settings
  • Step 2: No-load testing - Run motor without load, check for vibration and heating
  • Step 3: Load testing - Connect actual load, verify positioning accuracy and torque
Troubleshooting Guide
Symptom Probable Cause Solution
Driver red light, motor not rotating Overcurrent/overvoltage/undervoltage; wiring short Check motor windings; verify power supply voltage
Motor jitter and noise Low micro-stepping; insufficient current Increase micro-stepping to 1600+; set current to 6A
Positioning deviation Pulse signal loss; loose wiring Secure control wiring; maintain distance from power wires
Excessive motor heating High current setting; poor ventilation Reduce current to 6A; ensure proper heat dissipation
