hello

i use somove to program it and it is one problem
i have connected 4-20ma 1-10bar pressure sensor to altivar 12 and use the pid loop and it works fine bud it is one problem when i use 2 wire control it will not start, i always have to turn it on with the hmi on freq then it works great

bud when i change Macro config selection from pid regler to start/stop then i can use the 2 wire connecting

is somebody here who know how i can use the pid and 2wire control together
 
You should use a auto/manual select switch. And switch the command reference via a logic input. Look at the CTL menu (Control menu)
