10.2.4 Conditions for Selecting Peripheral Equipment of Servo
Amplifier
 To select peripheral equipment for a single servo amplifier
Obtain "1.5 times" the input current (Iin) obtained above.
 To select peripheral equipment for two or more servo amplifiers
Multiply "1.5 times" the sum of the input currents (Iin) of all servo amplifiers.
[Example] In case of two 200 W units and three 400 W units (In case of single-phase 200 V)
I = {(2.4 × 2) + (4.7 × 3)} × 1.5 = 28.35 A
Select peripheral equipment having 28.35 A or a larger rated current.
