Notes:

  1. When the power supply voltage drops, we cannot guarantee the output and rated speed.
  2. 80% ED at low noise. 80% ED: Indicates the condition in which operation time at read torque accounts for 80% and the other no load time accounts for 20% in a single operation cycle.
  3. When the servomotor is equipped with reduction gear or electromagnetic brake, refer to the corresponding outline dimension drawing. For the EN Standard and UL/cUL Standard compliant models, please contact Mitsubishi.
  4. If the load inertia moment ratio exceeds the indicated value, please contact Mitsubishi.
  5. When the equipment is to be used in places where it is subjected to oil and/or water, such as on machine field sites, optional features apply to the equipment.
  6. Except for the shaft-through portion and connector end.
