400V Class Inverters –The following tables
specify the braking options for 400V class
SJ200 inverters and the braking torque for
2
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.
