Hello, I use CU310-2 Pn V5.2 HF7 with 1FK2 servo motor. P2506[0] = 1000 (1000 LU per load rev.) and Load/Motor rev is 1/1. P2571 = 3000 * 1000 Lu/min (Max. Velo) corresponds to 3000 rpm. P2572 = 2500 * 1000 Lu/s*s (Max Acc.) corresponds to 20 ms for 3000 rpm (?) So when use EPOS MDI mode, I gave 1% for OverAcc and OverDec inputs of Sina_Pos Block and waiting for 2 seconds to 3000 rpm.(?) Time diagram of Device Trace show to me 300 ms for 3000 rpm and also 300 ms for 300 rpm. I couldn't see 100 or 50 ms never even i use 100% OverAcc and OverDec. I checked inputs of MDI/Diagnostics at STARTER. OverAcc and OverDec also there as i gave from tia_portal. Is there any parameters i skipped? AttachmentY.zip (72 Downloads) |

Hello, your calculations are correct in case you dont have a jerk limiting active. Check p2574 and p2575. Check also the MDI velocity at the input pin "Velocity". Nevertheless, there is something wrong in your project and I recommend to contact the technical support. Send also your TIA project, Starter project and trace files. https://support.industry.siemens.com/my/ww/en/requests/#createRequest |
