This is the web edition of the original ⮫ AC500-S safety user manual, version 1.3.2. This web edition is provided for quick reference only. The original safety user manual must be used to meet functional safety application requirements. |
This example shows the usage of the diagnostic concept, with a daisy chain from the FB parameters Activate and Ready (with perhaps a pre-evaluation of hardware errors). Other examples will not show the diagnostic connections.
⮫ “Example 3: two-hand control”
The safety functionality is to stop a drive in accordance with stop category 1 of IEC 60204-1 initiated by an emergency stop or by interrupting the light curtain. The equivalent monitoring of the 2 connectors of the emergency stop switch is done in the safety application.
In this example, both options of input evaluation are shown:
-
via intelligent safety input
-
via the equivalent function block
