text: <s>[INST] Powerflex 700 fault Hi, We have experienced a few Powerflex 700 drive - Fault 24 (Decel Inhibit) errors over the last week. The drive supplies 2 motors in parallel on a printing press reelstand. We initially changed the drive but the fault occurred again. Every time it has happened the press was running at speed but was NOT decellerating. As each motor had an encoder on it, I have now swapped to the alternate encoder in the hope that this cures the fault but after reading the handbook, I'm not sure it will. Any ideas on possible causes? I imagine the next step will be to start swapping the motors over to eliminate them.
