3.4.1 Determining the current consumption
The current consumption of a CMAX system depends on the
number and type of the modules connected to the axis inter
face.
Recommendation:
·
Use a closed−loop regulated power supply.
·
When selecting the power supply unit, check that it pro
vides a sufficient output. Calculate the total current con
sumption, if necessary.
Calculations Tab.3/10 and Tab.3/11 show the current consumption for a
positioning system.
Observe the instructions on selecting the power supply unit
in the CPX system description.
