7-3-2 Selection from input current
Use the following table to select the contactors so the total input current for each unit does not exceed
the rated continuity current.

The contactor is selected for the MDS-B-SVJ2-10 with 4 HC102 axes and an MDS-C1-CV-55
connected.
< Selection from rush current >
(SVJ2-10 × 4 axes rush current) + (MDS-C1-CV-55 rush current) = 4 × 100A + 15A
= 415A
Therefore, S-K50 200VAC.
< Selection from input current >
(HC102 × 4 axes input current) + (MDS-C1-CV-55 input current) = 30A + 30A = 60A
Therefore, S-N35 200VAC.
From these, the S-K50 200VAC is selected as having the larger of the two capacities.
