STEP 3 - Calculate the external 24 Vdc supply requirements, EMC filter required and quantity of Multi axis kits
needed
With reference to Table 5-7 24 Vdc typical input current and power requirements, the external 24 V current demand will be:
Table 5-8 24 V supply requirements for application example
EMC filter
The external EMC filter can be selected by input current rating using the following formula:
Input current (A) = a x P(kW)
2
+ b x P(kW) + c
Where constants a, b and c are given in Table 5-9:
Table 5-9 Input current equation constants
Input current (A) = -0.2 x 9.6
2
+ 6 x 9.6 + 0.5
Input current (A) = 39.67
Suitable external EMC filter (refer to Table 6-37

Multi axis kits
As both the M753-02400105 and M753-03400160 (axis C and axis D respectively) require SI-option modules and axis A and B do not, the following
multi axis kits are required:
