text: <s>[INST] PF400 Commanded Freq. via a Remote HIM will be replace by Max. Freq when ESC is being press Hi all,I have this serious problem with powerFlex 400, the application is for Chiller. so there were two operation Remote(PLC) and Local. in Local mode, I used a push Button and a Remote HIM( 22-HIM-C25), the problem is in the Commanded freq. when ever i Press Up or Down key to set a speed and press enter or save. and press esc button, and if you happen to press again the up and down key incase you want to change again. the Commanded freq will shot up to the Maximum freq. this is weird and very unsafe..anybody can help... please.. Gnix [/INST] I've heard about this problem before, as far as I can remember this happen only when P034 (Minimum Freq) is set to a value different than 0... try to set it to 0 and see if it solves. I don't know if it is solved in the last 6.01 firmware ... :smileysurprised: - fuzzy logic \\n </s>
