12. OPTIONS AND AUXILIARY EQUIPMENT

(2) Selection example

Indicated below is an example of selecting a leakage current breaker under the following conditions:

Servo

amplifier

MR-J2S-60B

Servo motor

HC-MFS73

Ig1 Ig2

Iga

Igm

2mm

Use a leakage current breaker designed for suppressing harmonics/surges.

Find the terms of Equation (12.2) from the diagram:

Ig1

1000

0.1

[mA]

Ig2

1000

0.1

[mA]

Ign

0 (not used)

Iga

0.1 [mA]

Igm

0.1 [mA]

Insert these values in Equation (12.2):

10 {0.1 0 0.1 3 (0.1 0.1)}

4 [mA]

According to the result of calculation, use a leakage current breaker having the rated sensitivity

current (Ig) of 4[mA] or more. A leakage current breaker having Ig of 15[mA] is used with the NV-

SP/CP/SW/CW/HW series.
