text: <s>[INST] Keep Motor Warm with DC Brake Function Summary: How to setup PF70EC DC Brake to keep motor warm Hi All, I have setup a Powerflex 70EC VFD to DC Brake indefinitely when the VFD is not running, and while it appears I have done everything correctly, it does not appear to engage. I'm using Digital Input 6 set to Stop Mode B which is set to DC brake after a 10 second delay. When the drive is on and not running there is 24V on Digital In6 and nothing is suggesting that it's working. The only thing I can think of right now is that maybe I can not engage a stop command after the drive is not running - Please comment. Here are my parameters: 156 Stop Mode B = DC Brake 158 DC Brake Level = 1 Amp 366 Digital In6 = Stop Mode B 384 Digital Out2 = Run 386 Dig Out2 OnTime = 10 Seconds Here is the IO wiring: [/INST] I really don't think permanent DC braking is a solution for keeping the motor warm; excessive DC braking could and most likely will deteriorate your AC motor's windings insulation. Refer to Page 197 of http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/pflex-rm001_-en-e.pdf for the detailed description of the PF 70-700 DC Brake functionality. If you are trying to avoid condensation you might need to deploy space heaters or choose a totally enclosed type of motor (if there are no water vapors within the windings there will be no condensation!). \\n </s>
