This section provides dynamic braking details for L100-M Series configuration corre-
sponding to Chapter 5, “Inverter System Accessories,” in the L100 Inverter Instruction
Manual.
Selecting Braking Resistors for External Braking Units
The following tables specify the braking
options for L100-M inverters and the braking
torque for each option. You can connect a
single braking unit to the inverter, or two
braking units for additional stopping torque.
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.
