Applicable Industries:
- Small packaging machines
- Conveyor systems
- 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
