Selecting Braking Resistors for Internal Braking Units

You can add one or more resistors to your inverter configuration to increase braking torque performance. The tables below lists the resistor types for inverter models with internal braking units. Tables for inverters with external braking units are on the next two pages.

•Total Ohms – lists the resistance value of the resistor or, if using multiple resistors, their combined resistance

•Total Watts – lists the power dissipation of the resistor or, if using multiple resistors, their combined power dissipation

•Maximum Duty Cycle – the maximum allowable percentage of braking time over any 100-second interval to avoid overheating the resistor(s)

•Maximum Braking Torque – the maximum braking torque that the inverter / resistor combination can deliver

The table below lists 200V-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.
