text: <s>[INST] PF 400 output frequency problem Summary: drive is not running on commanded frequencyCustomer have power flex 400 Ac Drive, 125Hp. They are using it for Agitator application. For first 12 hour they run drive on 25 Hz its working ok, After that they run it at 50Hz but in this condition drive output frequency automatically reduce from 50 hz to 43 Hz. observed commanded frequency is 50 Hz, output current decreses when output freq decreases. I have already told them to increase the current limit 1 and 2 and disable, drive OL mode parameter. WHAT ELSE CAN BE DONE TO OVERCOME THIS ISSUE ? NEED YOUR SUGGESTIONS. Thanks [/INST] What value is set in parameter A175 (Slip Frequency)? Try setting this to value 0. Is there a non-zero value set in parameter A188, A190, A192 (skip frequencies)? Set them back to zero if so. \\n </s>
