Note: 1. When the power supply voltage drops, we cannot guarantee the output and rated speed.
2. 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. Please contact.
3. The power supply capacity depends on the power supply impedance.
4. The regenerative brake duty indicated is the permissible duty when the servo motor run-
ning without load at the rated speed is decelerated to a stop. When a load is connected,
the value in the table is multiplied by 1/(m + 1), where m = load inertia moment/motor
inertia moment. At the speed higher than the rated, the permissible number of times is in
inverse proportion to the square of (running speed/rated speed). When the running speed
varies frequently or when the regenerative mode continues as in vertical feed, calculate
regenerative heat generated during operation. Provisions must be made to keep this gen-
erated heat below the permissible value.
5. If the effective torque is within the rated torque range, there are no restrictions on the
regenerative duty.
6. If the load inertia moment ratio exceeds the indicated value, please consult us.
7. When the servo motor is equipped with reduction gear or electromagnetic brake, refer to the
corresponding outline dimension drawing. For the EN Standard- and UL/C-UL Standard-com-
pliant models, please consult us.
8. Except for the shaft-through portion and connector.
9. HC-UF73, HC-SF203, and HC-SF353 may not be connected depending on the production
period of the servo amplifier. For details, contact us.
