■When connecting one simple converter and multiple servo amplifiers
Circuit breakers, semiconductor fuses, or motor circuit breakers (Type E combination motor controllers) that match the sum of
the rated capacities [kW] of the multiple connected amplifiers can be used. The selection condition is as follows. When using
a multi-axis servo amplifier, calculate the sum of the rated capacities of all axes as the rated capacity of the servo amplifier.
The sum of rated capacities of connected servo amplifiers [kW] ≤ 3 kW (MR-CM3K rated output)
