INTELLIGENT ACTUATOR
Part 1 Installation
 Calculation
example)
A 3-axis controller with a brake, equipped with a 200-W actuator for axis 1, 200-W actuator for axis 2
and 100-W actuator for axis 3

Power-source capacity
The motor drive power is 252.6 W for axes 1 and 2 and 140.1 W for axis 3.
The control power-source capacity is calculated as 39.1 W for “3-axis controller/brake x 1.”
(252.6 + 252.6 + 140.1 + 39.1)  0.6  1141 [VA]
The power-source capacity is 1141 [VA].

Heat output
The output stage loss is 9.12 W for axes 1 and 2 and 6.12 W for axis 3.
The control power-source capacity is calculated as 39.1 W for “3-axis controller/brake x 1.”
(9.12 + 9.12 + 6.12) + 39.1  63 [W]
The heat output is 63 [W].
