For how to select a power supply module (PSMV–HV), see Section 3.3,
and for the rated output capacity, see Table 4.2.1 (3).
When two α6/3000 servo motors, one α22/2000 servo motor and one α3
spindle motor are used
α6/3000 servo motor
Continuous rated output : 1.4 kW
Accelerating maximum output : 6.2 kW
α22/2000 servo motor
Continuous rated output : 3.8 kW
Accelerating maximum output : 7.5 kW
α3 spindle motor
Continuous rated output : 3.7 kW
Accelerating maximum output : 6.6 kW

= 6.6×(6.2 2+7.5) 0.6
= 18.54 (2)
As the rated output capacity of the power supply module is less than 11
kW, the following formula is used for calculating the maximum output ca-
pacity:
×0.6
Based on (1) and (2), the PSM–11HV is selected.
