Hey my existing propportional gain the automatically set value is 2.0 integral 20ms but I have tried a thousand variations of these values and still cant seem to get a steady output.
I am trying to tune a PID controller to control a motor via a variable speed drive. The vsd used is a siemens micromaster 410 and ramp up and down times are low (1.5). I cant seem to get the speed output to remain steady. When in manual mode it produces a perfect steady output but in automatic...
first time user here so go easy on me.
The encoder is an siemens incremental encoder but it is the PLC program that is the problem however I think I have it sorted now.
I will know for sure tomorrow when I return to my PLC however my SFC program is press start button motor comes on at set...
Hi I am trying to control the position of an encoder using step 7.
I want the position to change when the set point demands it so if position 1 is 10 and position 2 is -10 this would activate a change? I tried using a comparator block but if the tird position is -20 this activates a change...

Hi I am doing a project where I control a motor using siemens plc, vsd and scada wincc. I want to have 3 different sequences and using the Scada recipe function call sequence 1, sequence 2 and sequence 3 at different times etc. how can I do this using the recipe function? I have the sequences...
