(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 four HS-SF102 axes and one
MDS-B-CV-55 connected.
< Selection from rush current >
(HS-SF102

4 axes rush current) + (MDS-B-CV-55 rush current) = 4
×
100A + 15A
= 415A
Therefore, S-K50 200VAC.
< Selection from input current >
(JS-SF102
×
4 axes input current) + (MDS-B-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.
4-2-4 Circuit protector
When installing a circuit protector dedicated for the control power input, use a circuit protector with
inertial delay to prevent malfunctioning in respect to the rush current generated when the power is
turned ON. The size and conductivity time of the rush current fluctuate according to the power supply
impedance and potential.
