Responding to: ???'s previous message
can you explain a little more in detail about the motor what is the power rating,does it has an encoder attached if your motor rating is about 3/4 of a hp and has an encoder goes with it I might be able to send you a design of mine, couple of years back i designed a controll board for Vamatex terry loom it is a rapier type shuttle i used triac and a FtoV LM2907 ic built 40 units and still working some company sold you very weird design and went bankrupt left you holding thin air!

         It doesn't have to be so bad if you switch at zero crossing            01/01/70 00:00      
            and give tyhe AC motor every other cycle ????            01/01/70 00:00      
               No ... just turn it on and off at zero crossing            01/01/70 00:00      
                  it is an AC motor, details, details, detalis            01/01/70 00:00      
                     Horrible motor control            01/01/70 00:00

                        on and off at zero crossing....            01/01/70 00:00      
                           and if you cut only half cycles ....            01/01/70 00:00      
                              Nope ... it just happens at power-on and power-off            01/01/70 00:00
