Notes:
- When the power supply voltage drops, we cannot guarantee the output and rated speed.
- 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.
- 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.
- If the load inertia moment ratio exceeds the indicated value, please contact Mitsubishi.
- 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.
- Except for the shaft-through portion and connector end.
