PowerFlex 525 Troubleshooting

Hello everyone!

I am having issues with my PowerFlex 525 drive pulling in a brake on a Baldor motor. I have tried everything I know to do. The brake will pull in if I use a motor starter, but if I try to run through the VFD, the brake tries to pull in but does not have the full voltage to pull it all the way in. I have tried adjusting the brake and the Start Boost (A531) but still no luck. The motor is wired for high voltage. Any advice will be greatly appreciated!

460V 3 Phase

Baldor Motor

Thank you,
