Igm (C-axis))} [mA] . . . (6.2)
Ig1: Leakage current on the electric channel from the earth-leakage current breaker to the input terminals of the servo
amplifier
Page 225 Example of leakage current (Ig1, Ig2) per km of CV cable run in metal conduit
Ig2: Leakage current on the electric channel from the output terminals of the servo amplifier to the servo motor
Page 225 Example of leakage current (Ig1, Ig2) per km of CV cable run in metal conduit
Ign: Leakage current when a filter is connected to the input side (4.4 mA per one FR-BIF(-H))
Iga: Servo amplifier leakage current
