I have a idec pentra fc5a 24volt and I am trying to use the frequency option to count pulses on a three toothed rotor from a snowmobile engine, then convert to a 0-10 volt signal to send to a vfd which is running a water pump. I need the water pump to increase and decrease in speed in relation to the snowmobile engine. The pump is running into a water brake dyno. Right now there is about a one second lag in the system. I have gone through all the wiring and tried different programming but no use. So I phoned idec tech and they said there is a one second calculation period for this option. Why would they make according to them, the worlds fastest micro plc and then slow it down. Does anyone know of a way to get around this or am I looking for another plc.
