  • Mounting:​ Panel mount within enclosed cabinet.
Working Principle:​
The drive receives motion commands via DeviceNet, processes them through its DSP/RISC core to generate PWM sine-wave outputs, and closes current, speed, and position loops using motor feedback signals for precise torque, velocity, or position control.
Application Scenarios:​
Small-scale automation axes, packaging machines, lab automation, textile machinery, medical diagnostic equipment where DeviceNet networking is required.
Installation Requirements:​
  • Install inside a closed control cabinet with adequate ventilation.
  • Ensure proper grounding of chassis and shield termination.
  • Maintain clearance for airflow; avoid high-vibration locations.
  • Connect 24 V DC control power independently if needed for holdup.
Usage Precautions:​
  • Do not operate above 1500 m altitude without accounting for power derating.
  • Avoid condensation (5%–95% RH non-condensing).
  • Verify DeviceNet node address and baud rate before commissioning.
  • Use only specified external shunts for regenerative energy management.
