  • Small CNC machines
  • Robot joints (small payload)
  • Textile machines (single-axis)
  • Laboratory automation

Installation Requirements:

  • Mount with ≥ 50 mm clearance on all sides for ventilation
  • Use external braking resistor rated for 200W servo systems (for vertical axis or high-inertia loads)
  • Install external EMC filter per local EMC regulations
  • Connect 24 VDC control power before applying main power
  • Ground the chassis to earth ground (≤ 100 Ω)

Usage Precautions:

  • Do not operate without an external braking resistor for vertical-axis or high-inertia applications
  • Verify encoder signal compatibility: 5V differential line driver (RS-422A) or open-collector (5–24 VDC)
  • Perform auto-tuning after any motor replacement or mechanical change
  • Do not exceed the peak current rating for more than 3 seconds
  • Derate output power by 1% per °C above +35°C ambient temperature
