Switch to make Arduino controll a VFD
hi.
wonder if i'm thinking may done arduino way i'm thinking it.
i have 5 position switch.
i want control vfd (that again control engine).
the vfd has ground (grnd) , 4 digital inputs (x1, x2, x3, x4). different combinations give different values. x1 on. x2, x3 , x4 defines speed. example:
grn x1 + x2 engine starts @ lowest speed.
grn x1 + x3, engine starts @ second speed
grn x1 + x2 + x4, engine starts @ max speed
when measure grn x1 5v.
the idea should able connect grn on switch grn on ardino grn on vfd.
the switch pos1 connected pin 1 arduino, pos 2 pin 2 , on position 1-5
pin 7 connected x1 on vfd, pin 8 x2 on vfd , on
when switch closes, example pos 2, cause input signal on pin 2.
when arduino reads pin 2 output high on pin 7 , 9 , start engine @ slowest speed.
will work, can connect grn on arduino board , vfd same ground? , if can send signals arduino vfd? dont want tray out, in case might fry vfd - not thing.
totally newbey input appriciated.
regards, tek

don't take wrong way sounds guessing. have not posted datasheet. seem making assumptions operation mode of vfd. (would nice if people took time explain abbreviations ?)
so seem have variable frequency drive ? how relate engine ? engine ? going
give part numbers or concrete data @ ? how datasheet ? thing have numbers on ?
do know @ other end of these wires "x" labels ?
how supposed answer without knowing talking ?
