400V Class Inverters –
The following tables
specify the braking options for 400V class
SJ100 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–E2 braking unit for the braking torque listed in the following table.
Connect a second braking unit in parallel for additional braking torque listed in the
following table.
