Hi Experts ; Can I use an analog sensor to measure the bed moving speed in one direction? It s mean when moving the machine bed in one direction analog value change 4 ma to 2o ma. Here I have attached the written program, but it is not correct. I'm trying with the below calculation. Velocity = (PositionNow - PositionEarier) / TimeSpan Please help me with that.

See attachment for a possible solution with Min/Max blocks. The time span is given with B001. The first value is stored in B003, the second value in B004. In B005 you have the difference between both values. Block B008 checks the sign of the difference to get only positive values in block B006. Use parameter P2 and P3 of block B006 to scale the speed in your desired unit. Maybe the time span must be increased, if the differences are too small in your application.
