3-2-2 Heating value
Each heating value is calculated with the following values.
The values for the spindle drive unit apply for the continuous rated output. The values for the power
supply unit include the AC reactor's heating value.

(Note 1) The values for the spindle drive unit are the heating value at the continuous rated output.
(Note 2) The total heating value for the power supply includes the heating value for the AC reactor.
(Note 3) The total heating value for the unit is the total sum of the heating values for the above
corresponding units which are mounted in the actual machine.
Example) When the CV-185, SP-185 units are mounted
Unit total heating value (W) =195+242=437(W)
