Allen Bradley Kinetix5500 STO control by Omron safety controller

[cocoroco89]

Hello,

I have an inquiry about controlling Servo drive STO(Safety Torque Off) by following components.

-. SERVO DRIVE: 2198-H040-ERS2
-. PLC Controller: 1769-L33ERM
-. Safety Controller: G9SP-N20S

Would it be possible to control STO with the components above?

As far as I know, it won't work. The alternatives would be:

1) Hard-wired STO.
2198-H040-ERS
1769-L33ERM
G9SP-N20S

2) GuardLogix
2198-H040-ERS2
1769-L3xERMS

Your item #1 is what the OP listed?

Why won't it work?

Hard-wired STO can generally be switched by any safety controller or safety relay.

It is just a set of monitored safety inputs on the drive.

I don't see why it wouldn't work.

P.S. Jeev... Viscount?

ERS and ERS2. ERS comes with the STO terminals for a hard-wired STO. The ERS2 issues the STO over ethernet, and the spot where the terminals would be is blanked over.

Same guy

Thanks to all.
I got the answer from RA that the component list I mentioned wouldn`t work. ERS2 servo drives require integrated safety controller that can issue STO command over Ethernet. It is shame that ERS2 blanked STO terminal block. It would have been so much more flexible to either cases of hardwired STO or STO over Ethernet.
