Installation & Notes:
  • Motor must be grounded to protective earth via PE terminal.
  • Brake releases only when 24 VDC is applied — verify brake voltage/current rating.
  • Use correct motor-to-drive commutation parameters (resolver offset) during auto-commissioning.
  • Do not exceed max. radial/axial shaft load specified in datasheet.
