11 - 53 11. OPTIONS AND AUXILIARY EQUIPMENT
(b) Example of selecting the wire sizes When connecting multiple servo amplifiers, alwa ys use junction terminals for wiring the servo amplifier terminals P, N. Also, connect the servo amplifiers in the order of larger to smaller capacities. 1) 200V class R2/L1

First unit:
50mm2 assuming that the total of servo amplifier
capacities is 27.5kW since 15kW + 7kW + 3.5kW
+ 2.0kW = 27.5kW.

Note. When using the servo amplifier of 7kW or less, make sure to disconnect the wiring of built-in regenerative resistor (3.5kW or
less: P-D, 5k/7kW: P-C).
