Working Principle

Three-phase AC mains filtered by internal EMC circuit enters rectifier bridge to generate DC bus voltage; dual-core processor receives real-time motion commands via EtherCAT/CANopen bus, computes instantaneous torque reference value, outputs high-frequency PWM drive signal to IGBT power stage to generate three-phase variable-frequency variable-amplitude sinusoidal drive current for servo motor. Encoder feedback transmits rotor position data back to processor for closed-loop real-time correction; STO hardware circuit cuts power stage output instantly once safety trigger signal is received to eliminate motor torque output.

Applicable Industries

CNC machine auxiliary axes, semiconductor wafer handling equipment, precision printing machinery, automated robotics joint axes, food packaging high-speed cutting equipment, lithium battery winding machinery, optical inspection precision stages

Installation Requirements

  1. Mount on standard 35 mm DIN rail vertically; top heat dissipation gap ≥ 60 mm, bottom gap ≥ 40 mm
  2. Separate high-power motor cable and low-signal encoder/EtherCAT cable routing with metal shielding
  3. Drive protective earth terminal connected to cabinet grounding bus with minimum 2.5 mm² copper wire
  4. Ambient operating temperature range: -10°C ~ +40°C; temperature above 40°C implement linear power derating
  5. Cabinet internal forced air cooling required if multiple S700 drives are densely arranged

Usage Precautions

  1. Do not short-circuit DC bus positive and negative terminals; immediate power module burnout occurs
  2. Verify STO safety circuit wiring before equipment formal operation to avoid unexpected motor movement
  3. When matching high-inertia load, install external brake resistor to prevent DC bus overvoltage alarm during rapid deceleration
  4. Firmware upgrade only via official Kollmorgen Workbench software; third-party firmware will lock hardware
  5. Avoid installation position near high-power frequency converters or welding equipment with strong electromagnetic interference
