Accessories and Dimensions Appendix B
(1) The resistors listed in this tables are rated for 5% duty cycle.
(2) Use of Rockwell Automation resistors is always recommended. The resistors listed have been carefully selected for optimizing
performance in a variety of applications. Alternative resistors may be used, however, care must be taken when making a selection.
See the PowerFlex Dynamic Braking Resistor Calculator, publication PFLEX-AT001.
(3) Requires two resistors wired in parallel.
(4) Requires three resistors wired in parallel.
