Note:
1. Select braking resistors according to the resistance and power data provided by INVT.
2. The braking resistor may increase the braking torque of the VFD. The preceding table describes
the resistance and power for 100% braking torque, 10% braking usage, 50% braking usage, and
80% braking usage. You can select the braking system based on the actual operation conditions.
