Delta Electronics AC Motor Drive VFD-G - Manual (Page 164)

Revision July 2008, EG03, SW V1.06 B-1
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 460 V series, 100 HP, AC drive has 2 brake units with total of 16 brake resistors, so each
brake unit uses 8 brake resistors. There should be at least 10 cm away from AC drive to avoid
possible noise. Refer to the “Brake Unit Module User Manual” for further detail.
