Good morning Sirs,
My bosses would like to perform a positioning, to actuate a lift, with a SEW asynchronous motor and a PF (until now a PF 40P). A Rockwell technician came here and said we'd have to use a special program for the PF a use a 4-wire encoder to perform this positioning. It doesn't have to be that precision, but it can't lose the point every time I use it, or after some actions it will be out of my work point.
I was thinking of using the encoder on my PLC (ML1400) and send some signals to it, such as "reduce speed" and brake commands. When my encoder performs "n" pulses I'll send a reduce signal and after more "n" pulses a brake signal.
My point is: the PF with my asynchronous SEW motor can perform that positioning the way I said, with my ML1400 sending those commands? The set of this lift isn't too heavy, at least I think.
Thanks in advance.
