The table below lists 400V-class inverter models
with built-in braking units. Depending on the
desired braking torque or on the inverter model,
the resistor selection specifies multiple resistors
in a parallel or series combination. The example
diagram shows a parallel configuration. Please
refer to the braking resistor documentation for
detailed wiring diagrams.
Selecting Braking Resistors for External Braking Units
200V Class Inverters – The following tables
specify the braking options for 200V 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 stopping torque.
