Appendix B Accessories
B.1 All Brake Resistors & Brake Units Used in AC Motor 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 460V series, 100hp/75kW, the AC motor drive needs 2 brake units with total of 16
brake resistors, so each brake unit uses 8 brake resistors. The brake unit should be at least 10 cm
away from AC motor drive to avoid possible interference. Refer to the “Brake Unit Module User
Manual” for further details.
