I don't think I understand how to use the Dynamic Braking options for the Powerflex 4/40 drives.
I have a Powerflex 40, and a properly sized Dynamic Braking resistor. I'm trying to quickly slow down a high speed motor when I drop out the Run/Forward command.
If I set the Stop mode to Ramp, I can quickly slow it down, but if I go too fast, I get an F05 alarm, Overvoltage.
I installed the braking resistor on the BR+/- terminals, but I do not believe I understand how to set A080, A081, and A082. The protection, DB Level, and DB Time options.
If I set the Stop mode to DCBrake, leave the A081 to the default Drive Rated A x 0.05, and set the A082 to 4.0 seconds, the drive turns off, and the motor just coasts.
My motor is a 380V 3 phase, 300HZ, 18000 RPM, 4.0A full load.
My Powerflex 40 is rated 480V 6.0A
I think my problem is I don't understand the Dynamic brake settings enough to comfortably play around with the settings. The User Manual for the Powerflex 40 doesn't explain the meaning of the settings very well.
