Working Principle

Three-phase AC input rectifies to shared high-voltage DC bus; internal IGBT power module converts DC to variable-frequency three-phase AC for servo motor drive. High-speed DSP processes encoder feedback signal to adjust PWM output dynamically. Shared DC bus enables regenerative energy from decelerating axes to power accelerating axes; excess energy dissipated via external braking resistor. STO safety circuit cuts IGBT drive signals immediately upon safety trigger to eliminate motor torque output.

Applicable Industries

Printing press equipment, metal forming machine tools, automated packaging lines, robotic palletizing systems, woodworking CNC machinery, injection molding auxiliary servo axes, textile high-speed looms

Installation Requirements

  1. Vertical wall mount inside IP54+ industrial electrical cabinet, no horizontal installation allowed
  2. Top and bottom minimum 80 mm convection cooling clearance required
  3. Power cable shield layer must be 360° clamped to cabinet metal ground bar
  4. Shared DC bus wiring strictly follow manufacturer specified cross-section copper cable
  5. Cabinet forced air cooling required for continuous full-load operation above 35°C ambient

Operation Precautions

  1. Verify three-phase input phase sequence before first power-up
  2. STO safety circuit wiring must implement dual-channel redundant design
  3. Do not hot-plug power or feedback connectors under energized state
  4. Perform quarterly heat sink dust cleaning to avoid overheating shutdown
  5. Comply with CE, UL, TÜV safety certification wiring specifications
