Is there anyone here familiar with the Siemens Micromaster 420 VFD?
The thing has 3 programmable digital inputs, and an additional analog one that could be programmed as a digital input too.
Is there a way to configure those inputs so as to have three pushbuttons to control it, with two limit switches?
What I want to accomplish is really simple:
What I'd like to avoid is adding relays as logic gates to accomplish what I want.

What I want to accomplish is really simple:
- A momentary NO button to start it forward, and stop when the +limit switch is activated
- A momentary NO button to start it in reverse, and stop when the -limit switch is activated.
- An emergency stop button.
