If this value is 2 to 3%, use an optional AC reactor (ACR).
*6 Required when a DC reactor (DCR) is used.
*7 Average braking torque for the motor running alone. (It varies with the efficiency of the motor.)
*8 A DC reactor (DCR) is optionally provided. Note that inverters with a capacity of 55 kW in LD mode and inverters with 75 kW or above in all modes
require a DCR to be connected. Be sure to connect it to those inverters.
Note: A box () in the above table replaces A or E depending on the shipping destination.
