Delta VFD022B21A - All Braking Resistors and Braking Units Used in AC Motor Drives; Appendix B Accessories

Revision 10/2005, BE13, SW V4.08 B-1
Appendix B Accessories
B.1 All Braking Resistors & Braking 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 braking units with total of 16 braking resistors, so
each braking unit uses 8 braking resistors. The braking unit should be at least 10 cm away from AC motor
drive to avoid possible interference. Refer to the “Braking Unit Module User Manual” for further details.
