(2) Calculation of spindle maximum momentary output
The spindle maximum momentary output is calculated from the following expression.
Spindle maximum momentary output
=MAX (short-time rated output x 1.2, output at acceleration/deceleration x 1.2)
(Note) For the spindle rated output, use the larger one of "short-time rated output x 1.2" and "output at
acceleration/deceleration x 1.2".
7-3-2 Calculation of servo motor output
(1) Selection with rated output
(2) Selection with maximum momentary output
For the rated output and maximum momentary output of the servo motor, use the value corresponding to the
servo motor in the table 3.
Table 3. Data for servo motor output selection

< 400V series >
(Note) The maximum momentary output in this table is reference data for selecting the power supply
unit and is not data which guarantees the maximum output.
