NX safety slice alternatives

8 posts in this topic

The lead times are extremely long for NX series safety slices. Does anyone have any suggestions for an alternative? We can get the NX safety PLC but not enough slices. Are there third party external safety I/O boxes that will work with Sysmac Studio and the NX safety PLC?

If you have the NX-SL5XX you can use CIP safety remote IO (Omron or 3rd party). No support for 3rd party EtherCAT remote IO though.

We also have 1S series servos. Can the NX-SL5xx handle these with Safety over EtherCAT as well? I think the only way to do both is to couple the NX-SL5xx with the NX102 PLC. In this case you are limited to 8 servo axes. Is this right?

Correct, the SL5XXX needs to be on the NX102 for Ethercat Safety with a 1S. The NX102 can do 12 axis total, 8 coordinated axis.

In this case it will not work for us. Unfortunately. We have machines with 16 - 20 axes. Any other suggestions? This supply chain issue is really making life difficult.

Is the safety (either hardwired or FSoE) for the 1S drives primarily?

We have only been using FSoE for our 1S drives. It has been this way since we first started with Sysmac Studio and NX PLCs. So probably since around 2018 or so. Every machine that has come into the plant has been this way. No more hard wiring for safety.
