(1) When two α1/3000 servo motors and one α2 spindle motor are used
Servo motor α1/3000
Continuous rated output : 0.3 kW
Maximum output at acceleration : 0.9 kW
Spindle motor
α2
Continuous rated output : 2.2 kW
Maximum output at acceleration : 4.44 kW
Rated output capacity of a power supply module y Σ spindle motor
continuous rated output 1.15 + Σ servo motor continuous rated
output 0.6
= 2.2 1.15 + 0.3 2 0.6
= 2.89 Condition 1
Maximum output capacity of the power supply module y Σ
maximum output of the spindle motor at acceleration + Σ maximum
output of the servo motors at acceleration (simultaneous
acceleration/deceleration)
= 4.44 + 0.9 2
= 6.24 Condition 2
According to conditions 1 and 2, PSMR–3 is selected as the power
supply module.
(2) When two α2/2000 servo motor and one α6/2000 servo motor, and
one α3 spindle motor are used
Servo motor α2/2000
Continuous rated output : 0.4 kW
Maximum output at acceleration : 1.1 kW
