text: <s>[INST] Changing ACV Motor speed Tach feedback to DCV or 4-20ma HI , We would like to use our existing GE AC tach generator 90vac/1000rpm 180vac/2000rpm on a motor as a feedback to a DC drive. The drive will be similar to this 20hp 20P41AB073RA0NNN . This is for a conv belt, The drive excepts a DCv Tach feedback as well as 4-20 ma , 0-10v but not ACv. What converter is available to convert an AC Tach to DCv ? Or a converter to 4-20ma would also work. Note:The wave form of the AC Tach is not a square wave nor is it a nice sinusoidal shape.Frq is 265hz @400rpm. We have a few drives to upgrade and are comparing cost of an AC drive to a DC drive set up. I think a company called Mighty Modual may have what I need but if someone has been down this path before I would like to here their suggestions. Thank you! [/INST] Hi, Charles.
