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 3-phase 200V)
I = {(1.4 × 2) + (2.7 × 3)} × 1.5 = 16.35 [A]
Select peripheral equipment having 16.35 [A] or a larger rated current.
