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]}
Power factor [0.6]
Heat output [W] = Total sum of output stage losses [W] + Control power-source
capacity [W]

(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.)
