UR7 + DC OEM + Soft Start

Good morning,

I’m looking for some light in my setup (ur7e + dc oem).

For a first test, I’ve just connected the oem to a power supply providing 30V and limited to 10A and there, during the initialization of the arm, I’m getting the error C740A33.

After that, I tried with newer and better power supply and I managed to make it work but, investigating the problem, the suggestion I found was about the soft starter, that until now I didn’t have in the setup. I installed it (MM351R550DIN) and with it in the loop, none of my power supplies are able to make it work…

Do you have some insights or ways to make it work? Have I chose the wrong soft start module?

Regards,
