Hello
I have a -10V to +10 V signal from a device which I would to control a VFD with. The problem is that I need it to work like this.
-10V full speed reverse (and -5V is 50%)
+10V full speed forward (and +5V is 50%)
0V stop.
We have a lot of teco t-verter E2 series, so if they were able to do it, it would be great.
An other solution was to control it like this (because I also have a 0 to 10V signal available)
But then it would have to be like this:
5V means stop
From 5 to 10 V the motor runs one way ( 10V is full speed one way)
From 5 to 0 V the motor runs the other way (0V is full speed the other way)
I like the first method best because if connection is lost then the motor just stops. (it not dangerous but still)
hope for a reply
