[Calculation Example]
Shown below is an example for how to calculate the power capacity and amount of heat
generation when the following actuators are used.
SCARA Robot: IX-NNN1505H (without brake)
IX-NNN2515H
Standard Type Controller �Option: PIO Board 1 sheet, Device Net�
Teaching Pendant (IAI Standard Type)�

�
3) I/O (PIO board) Power Capacity (24V DC)�
14.52 × 1 = 14.52 [VA]
4) Brake Power Capacity (24V DC)
(2.5 + 1) × 1 = 7.0 [VA]
5) Motor Power Capacity
SCARA Axes IX-NNN1505H: 216.3[VA]
SCARA Axes IX-NNN2515H: 1863.1 [VA]
216.3 +1863.1 = 2079.4 [VA]
6) Motor Power Supply Heat Generation
8.13 + 44.8 = 52.93 [W]
7) Rated Power Capacity =
1) Control Power Capacity + 5) Motor Power Capacity = 150.1+ 2079.4 = 2229.5 [VA]
8) Heat Generation =
2) Heat Generation of Control System + 6) Motor Power Supply Heat Generation = 58.13
+ 52.93 = 111.06 [W]
