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 interĆ
face.
Recommendation:
· Use a closed−loop regulated power supply.
· When selecting the power supply unit, check that it proĆ
vides a sufficient output. Calculate the total current conĆ
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.
