Working Operating Principle

Wide-range AC mains input passes integrated EMC filter and full-wave rectifier to form shared DC bus rail. High-speed DSP executes FOC vector closed-loop control for servo motor current, velocity, and position regulation. Pre-programmed motion tasks stored in flash memory execute autonomously via digital input trigger signals; soft PLC module processes machine sensor logic without external PLC controller. DC bus parallel architecture allows excess regenerative energy from decelerating axes to supply accelerating axes within multi-drive cabinet systems.

Core Product Strengths

  1. 300-task motion program capacity supports complex automated machine cycle sequences without upper controller intervention
  2. DC bus parallel connection reduces regenerative braking resistor power consumption and cabinet heat generation
  3. Comprehensive multi-type feedback compatibility supports both new and legacy Kollmorgen servo motor models
  4. Embedded soft PLC eliminates separate PLC hardware for single-axis automated machinery, lowering total system cost
  5. UL, CE, cUL, EAC global industrial compliance certification for cross-region equipment deployment

Target Application Industries

Automated packaging machinery, textile production lines, woodworking CNC equipment, metal cutting small machining centers, printing converting machines, automated material handling conveyors, plastic injection molding auxiliary positioning axes.

Installation Mandatory Criteria

  1. Vertical mounting only; minimum vertical clearance top/bottom ≥40mm, horizontal side gap ≥75mm
  2. Operating ambient temperature: 0°C to 40°C; linear derate 2.5% output power per °C above threshold, maximum limit 55°C
  3. Ambient humidity range 10–85% RH with zero condensation allowed
  4. Installation altitude below 1000m sea level; derate 1.5% power per 100m elevation increase
  5. All motor and feedback wiring must utilize factory shielded cables with 360° metal shield grounding at both drive and motor terminals
  6. DC bus parallel connection requires matched drive current ratings; series bus interconnection strictly prohibited

Long-Term Operation Maintenance Rules

  1. Quarterly inspection of heat sink fin dust accumulation; low-pressure dry compressed air cleaning required for obstructed airflow
  2. Disconnect main AC power and wait minimum 10 minutes for capacitor discharge before chassis wiring maintenance
  3. Backup all motion program logic to external PC via RS232 port after commissioning to prevent flash memory data loss
  4. If STO safety circuit fault alarm activates, fully inspect all safety input wiring continuity and interlock switch contact integrity
  5. Avoid repeated rapid power cycling of drive unit; minimum 20-second interval between power-off and power-on cycles
  6. Operating vibration exposure maximum limit ≤0.5g; vibration isolation pads mandatory if installed adjacent to impact machinery
