Hello everyone,
I have a few questions i'm hoping someone can help with.
We have a fairly simple safety circuit
- two hand tie down
- light curtains
- gate latches
- e stop
I'm going to use one of the new Banner safety controllers (SC22) to manage all of the inputs.
My question is how do i then feed this to the PLC to function as a cycle start? Do i need to use two inputs on my PLC to maintain a 'safety' circuit? I would think using one input would undo all of the redundancy ahead of it.
Next question is in regards to servo drive - Specifically AB Ultra3000.
Upon a e stop situation, how do i interupt power to the motor? Is there a input into the driver for this? Do i place a set of contacts and kill power to the servo?
Sorry for the newbie questions - I'm just not getting quick responses on my questions from my venders
Thanks!
