Application Proposals for Software Based Safety-Related Function
Lexium 62 variants E/F are necessary to use software-based safety-related functions. Like Lexium 62 variants C/D/G, they also offer a dedicated two-channel input for a hardwired STO (Safe Torque Off) function.
In case the hardwired STO is not used, there is no need to connect it. In this case, the software-based safety-related functions use Sercos and OpenSAFETY.
Therefore, two application proposals are provided here for using or not using a hardwired STO function. When using the hardwired STO, the other software-based safety-related functions can be used, including the STO realized by software.
Application Proposal - Variants E/F Using Hardwired STO
|
Step |
Action |
|---|---|
|
1 |
Connect the Lexium 62 variants E/F like the variants C/D/G. |
|
2 |
Configure the safety-related network. |
|
3 |
Adjust the parameters, in particular the prioritization of Inverter Enable via hardware and STO (Safe Torque Off) via the bus. |
|
4 |
Program the EcoStruxure Machine Expert - Safety application. |
NOTE: Observe the information on the parameters in the EcoStruxure Machine Expert - Safety online help.
Application Proposal - Variants E/F Not Using Hardwired STO
|
Step |
Action |
|---|---|
|
1 |
Connect the Lexium 62 variants E/F as shown in the application proposals. |
|
2 |
Configure the safety-related network. |
|
3 |
Adjust the parameters, in particular the prioritization of Inverter Enable via hardware and STO (Safe Torque Off) via the bus. |
|
4 |
Program the EcoStruxure Machine Expert - Safety application. |
NOTE: Observe the information on the parameters in the EcoStruxure Machine Expert - Safety online help.
Application proposal for the control circuit (drawing number APP-111011-001):
There is no wiring required, as hardwired STO is not used. In this case, the software-based safety-related functions use Sercos and OpenSAFETY.
Application proposal for the load cycle (drawing number APP-111011-001):
