Our customer site has a few units Power flex 4 & 40 running at their machines.
A sensor (4-20mA) output is direclty wired into the analog input of the powerflex 4 & 40. Normally when the PF receive 4 mA it'll run at lowest speed, and the speed will increase propotional to mA input (until 20mA = highest speed).
Currently they need to invert the operation, whereby when the PF detecting 4mA, it'll run at full speed. The speed is inverse proportion to the mA input (max. 20mA = lowest speed).
Does PF4 or PF40 support this so call 'invert analog input' function?
Thanks a lot...
