(2)Selection example

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

NV

2mm25m2mm25m

Servo amplifier MR-J2S-60B

SM Servo motor HC-MFS73

Ig1 Iga Ig2 Igm

Use a leakage current breaker generally available.

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

Ig1	20	5	0.1 [mA]
		1000
Ig2	20	5	0.1 [mA]
		1000

Ign 0 (not used)

Iga 0.1 [mA]

Igm 0.1 [mA]

Insert these values in Equation (12.2):

Ig 10 {0.100.13 (0.10.1)}

8.0 [mA]

According to the result of calculation, use a leakage current breaker having the rated sensitivity current (Ig) of 8.0[mA] or more. A leakage current breaker having Ig of 15[mA] is used with the NV- CA/CS/SS series.
