(b) Example of selecting the wire sizes
When connecting multiple servo amplifiers, always use junction terminals for wiring the servo
amplifier terminals P, N-. Also, connect the servo amplifiers in the order of larger to smaller
capacities.

assuming that the total
of servo amplifier capacities is
15 kW since 7 kW + 3.5 kW +
2.0 kW = 12.5 kW.

assuming that the total of
servo amplifier capacities is 7kW
since 3.5 kW + 2.0 kW = 5.5 kW.
Third unit:

assuming that the total of
servo amplifier capacities is 2kW
since 2.0 kW = 2.0 kW.

Note. When using the servo amplifier of 7 kW or less, make sure to disconnect the wiring of built-in regenerative
resistor (5 kW or less: P and D, 7 kW to 7 kW: P and C).
