B.2 All Braking Resistors & Braking Units Use in AC Drives
Note: Please only use DELTA resistors and recommended values. Other resistors and values will void Delta’s
warranty. Please contact your nearest Delta representative for use of special resistors. For instance, in 460 V
series, 100 HP, AC drive has 2 braking units with total of 16 braking resistors, so each braking unit uses 8 braking
resistors. There should be at least 10 cm away from AC drive to avoid possible noise. Refer to the “Braking Unit
Module User Manual” for further detail.

Note:
1. Please select the factory default resistance value (Watt) and the frequency value (ED%)
2. If damage resulted in the drive or other equipments due to the fact that the braking resistors and the braking
modules in use are not provided by Delta, the warranty will be void.
3. Take into consideration the safety of the environment when installing the braking resistors.
4. If the minimum resistance value is to be utilized, consult local dealers for the calculation of the Watt figures.
5. Please select thermal relay trip contact to prevent resistor over load.
6. When using more than 2 braking units, equivalent resistor value of parallel braking unit can’t be less than the
value in the column “Equivalent Minimum Resistor Value for Each AC Drive” (the right-most column in
the table).
