help wiring inverter to car ramp

[justin221]

i think thats what i have not sure as the unit was pre made by rotor motor but i assume you mean the dial that adjusts the freq and is displayed in the screen is there any way i can just set the inverter to just give me 3 phas at 50hz thanks

sorry double post

yeah youre right, most inverters can be wired for a remote pot though which was what i was thinking of, set your minimum speed to 50hz and your maximum to 51hz and increase your ramp up time to maybe 2 sec, sorry if im repeating but what make is your inverter?

 

[pmac10]

just reread your parameters, you say youve set the pot to 50hz, what does that mean? is it possible youve set the speed source 0-10Vdc and the pot 4-20mA at 50hz??

no thats fine im bit new to this
its a ac tech sf250yf
ill just do it now and give it a go

thanks god its working that done the job all il have to do is pull in a 230 supply to the control circuit on the ramp it dont like running off one of the inverter phases

glad its working, as mentioned earlier, your inverter output is not true ac so never try to tap off it, its like a stepped square sine wave, but also you would create an imbalanced load on the output and most likely cause your inverter to trip out.
good luck.

Glad to see its working,should be a parameter which shows the current the motor is pulling, it would be worth while to check the current.
a clamp meter will not give an accurate reading!

You ned to put links in as per 11.2

2-12-13a-13b to tell it to run and in which direction

ok will check all of the above thanks guys
