text: <s>[INST] Power flex 750 series Max frequency Hello, I am trying to figure out why I cant run at 67 Hz when the speed reference is at 20 mA. At 4 mA I am at 0Hz, at 8 mA I am at 30 Hz and at 20 mA I am at 60 Hz. I changed parameter 0-37 to 67 Hz. wondering what am i missing ? Thanks [/INST] Welcome to Engage, Martinez! This can be increased by changing the setting to Parameter 520 [Max Fwd Speed] and Parameter 521 [Max Rev Speed] (depending on the direction). Analog Input parameters should also be changed.
