Purpose/procedure
(1)
---| |---NO contact:
"Deselection_<safety function>"
Example: "deselectionSs1"
or
Drive I/O address with ZSW bit
Address the PLC tag "Deselection_<safety
function>" or the drive I/O address, which
transfers the associated bit of the safety con‐
trol word.
(2)
---( )--- Assignment:
"DR_<drive number>_<safety function>"
Example: "drive1Ss1Disable"
or
Drive I/O address with STW bit
Assign the logic operation result to the safety
function in the drive involved.
(3)
Branch
If you deselect the safety function involved for
several drives, insert a branch and operation
for each drive (see 3a).
(3a) ---( )--- Assignment:
"DR_<drive number>_<safety function>"
Example: "drive2Ss1Disable"
or
Drive I/O address with ZSW bit
Assign the logic operation result to the safety
