text: <s>[INST] Powerflex 700 series A rev. 3.003 doesn't stop (error F24) Hi everyone. I have problem with one powerflex 700 drive. It happens when the drive tries to stop. It decelerate on 30 RPM in a few seconds and after that goes on 60 RPM and continue to run on that speed until error message decel inhibit (error F24). Any ideas. [/INST] User Manual gives indications about this fault... The drive is not following a commanded deceleration because it is attempting to limit bus voltage. Actions: 1. Verify input voltage is within drive specified limits. 2. Verify system ground impedance follows proper grounding techniques. 3. Disable bus regulation and/or add dynamic brake resistor and/or extend deceleration time. Refer to the Attention statement on page P-4 for further info. Parameter 238 bit 6 is the location to turn this fault on or off. By factory defaults this bit is on.Parameter 161, 162 and 160 are the bus regultation parameters that can be adjusted for application if the bus regulation is desired. See also Reference Manual for more infos about Bus Regulation. - fuzzy logic \\n </s>
