4.CONDITIONS FOR APPROVAL RELATED TO THE IEC60034 STANDARD SPECIFICATIONS FOR THE αiS/αi SERIES B-65262EN/03
- 86 -
4.2 APPROVED SPECIFICATIONS
The following specifications are approved for the IEC60034 standard.
4.2.1 Motor Speed (IEC60034-1)
The "rated-output speed" and "allowable maximum speed" are given
on the data sheet of each series in Part II and afterward.
The rated-output speed is the speed which specifies the rated output.
The allowable maximum speeds are specified in such a way that the
approval conditions of the IEC60034-1 standard, as they relate to
rotational speed, are satisfied.
When the allowable maximum speeds are used, the characteristics are
not guaranteed.
4.2.2 Output (IEC60034-1)
The "rated output" available with a motor is given on the data sheet of
each series in Part II and afterward. The rated output is guaranteed as
continuous output for the rated-output speed under Insulation Class F.
The output in an intermittent operation range is not specified. When
rated output increases due the use of an external fan, the servo motor
does not comply with the IEC60034 standard. Note, however, that this
poses no problem if the fan is used for the purpose of cooling, and the
motor is used with output held at the current output rating.
