400V Class Inverters – The following tables
specify the braking options for 400V class
L100 inverters and the braking torque for each
option. You can connect a single braking unit
to the inverter, or two braking units for
additional braking torque.
Use one BRD–EZ2 braking unit for the
braking torque listed in the following table.
