6 OPTIONS AND PERIPHERAL EQUIPMENT
6.3 MR-CM simple converter
Peripheral equipment
Molded-case circuit breakers, fuses, magnetic contactors
■
When connecting one simple converter and one servo amplifier
■
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)
