Configuration 7i92m_7i76x1D

I have some servo drives where you have to install a jumper to "fake" the limit signal if no limits are to be connected to them.

And I would definitely look into resetting the drives to their default parameter set

I have some servo drives where you have to install a jumper to "fake" the limit signal if no limits are to be connected to them.

Parameter P097=3 "Neglect inhibition of servo drive" - neglects all limit switches. More over, if it would not be neglected, then err 7 should be displayed, but not. Newer the less, I've connected DI3 and DI4, that corresponds to CCWL and CWL limits to ground (I didn't show it at scheme), meaning set to true, but nothing changed.

I will try that tommorow. I don't see any other ways anymore.

Are you sure you have the drives enable signals connected right?

Yes, I'm sure. I see that input is true on interface screen.

I've resettled servo to default but nothing. I suspect that problem in interface of command pulses. May be this one doesn’t supports.
In EP1C manual there are few ways to connect signals to the servodrive.

I use C3-1 differential drive, but may be I need to connect like in C3-2 - single end drive. If somebody know what 7i76 has inner scheme, tell me how to realize such connection.

The 7I76 has differential outputs and is very often used to drive servo drives with differential inputs
You can also drive single ended inputs with common GND or common 5V connections
