I have purchased A Velleman vm140 board , but having trouble with connecting it to my vfd s
I have looked at simulateur dynamique 2DOF MS-X-R, simulateur fonctionne on racingfr , translate it to dutch .
But I can`t understand how the vfd is connected using the digital out and the direction switches on the vfd
I have treid diff. things
using a external psu 24 volt connected to clamp , and digital out 08 to vfd directionswitch(S1) cw and digital out 07 S2 to ccw direction
I have connected the ground from the Psu to ground(gnd) on the card and common terminal on the vfd.
I`m thinking of connecting the + of the PSU to digital out 08 and 07 and then to the cw and ccu terminal on the vfd, but I`m not sure.
An Elektrik drawing will be nice
