Use one BRD–E2 braking unit for the braking torque listed in the following table.
Note the column meanings in the tables:
• Column “A” = Average braking torque from 60 Hz to 3 Hz.
• Column “B” = Average braking torque from 120 Hz to 3 Hz
Connect a second braking unit in parallel for additional braking torque listed in the
following table.
