text: <s>[INST] PowerFlex 753 go to maximum speed Hello, I'm using a PowerFlex 753 (7.5kW, 15A) AC drive. It takes the speed reference from the analog input. It works in closed loop. I'm using 20-750-ENC-1. But, for example, when the commanded frequency shows 12 Hz, it suddenly starts working at maximum speed. The version is 14.005. Any ideas what might be causing this issue? How can I solve it? Regards, [/INST] Hi, Programming Manual, Appendix A: Control Block Diagram: from here, find out the correct block diagram of your specific application Execute CCW to monitor your reference signal, actual feedback signal (shown on the block diagram), torque referece, actual torque, etc. Surely you can allocate where the problem is. Good luck! Terence \\n </s>
