Hi all Recently I have a problem with the control speed of a pump, for that control I'm using a SINAMICS G120 CU250S-2, with an 4-20mA analog input connected to AI0. The issue is as follows: When the pump starts for the first time the Hz corresponds to the mA, but after a while, the Hz decreases to the minimum speed value despite we increase the amount of mA to the VFD. I hope you can give me some advices to get it run. You can find my Project in the attachment. AttachmentP-4-2208.zip (145 Downloads) |
