3) I/O (PIO board) Power Capacity (24V DC)�
14.52 × 1 = 14.52 [VA]
4) Brake Power Capacity (24V DC)
(2.5 + 1) Ч 1 +(2.5 + 5.8) Ч1 = 11.8 [VA]
5) Motor Power Capacity
SCARA Axes: 3696.7[VA]
Single-Direction Axis: 421 + 234 = 655 [VA]
3696.7 + 655 = 4351.7 [VA]
6) Motor Power Supply Heat Generation
69.7 + 9.12 + 6.12 = 81.91 [W]
7) Rated Power Capacity =
1) Control Power Capacity + 5) Motor Power Capacity = 132.06+ 4351.7 = 4483.76 [VA]
8) Heat Generation =
2) Heat Generation of Control System + 6) Motor Power Supply Heat Generation = 55.66
+ 81.94 = 137.6 [W]
