text: <s>[INST] cannot get a Powerflex 755 drive to change direction Summary: i cannot get the Power flex drive to switch directions? FRW REV the key pad constantly shows rev [/INST] Bruce, if there's any chance you can upload a DNO file from DriveExecutive or whatever file format is used for Connected Components Workbench, that's the easiest, fastest way we could help you. There are several reasons why you might not be able to control direction from the HIM keypad. The drive could be configured for direction control via Ethernet or digital inputs from a PLC. The keypad could be masked from logical control. We'd be guessing at how you have the drive configured and take hours or days for back and forth communications. With the parameter file, any experts here would get you an answer in minutes. You can start looking at parameter 162 - DI Fwd / Reverse, and also at parameters 324, 325, 326 (various masks). If you do not have 750-PM001, get it here: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf You really cannot be in full control of a PF750 drive without this manual. Get us the parameter file one way or another and we'll get you a good answer. \\n </s>
