3. Power-Source Capacity and Heat Output of the Controller
The power-source capacity and heat output of the controller can be obtained using the formulas
below:
Power-source capacity [VA] = {Motor drive power [W] + Control power-source capacity
[W]} y Power factor [0.6]
Heat output [W] = Total sum of output stage losses [W] + Control power-source capacity [W]
Motor Drive Power and Output Stage Loss
Actuator motor wattage Motor drive power [W] Output stage loss [W]
20 W 15.6 1.58
30 W 27.6 2.07
60 W 83.0 3.93
100 W 140.1 6.12
150 W 196.9 8.30
200 W 252.6 9.12
400 W 477.5 19.76
600 W 698.2 27.20
750 W 912.8 29.77
The control power-source capacity varies as follows, depending on the numbers of controller axes and
brake axes.
Control Power-Source Capacity
No BK BK X 1 BK X 2 BK X 3 BK X 4
1-axis controller [W] 17.5 27.3
2-axis controller [W] 23.4 33.2 42.9
3-axis controller [W] 29.3 39.1 48.8 58.6
4-axis controller [W] 35.3 45.0 54.8 64.5 74.3
(In the above table, the number of controller axes indicates the number of axes connectable to the controller. It is not
the number of axes actually connected.)
