6.2 Reset and Status over Fieldbus

6.2.1 Reset of Safety Option and Pending Safe Function

There are 2 different methods of resetting the safety option and pending safe function. The configuration of parameter 42-31 Reset
Source is decisive for which method to use.
If parameter 42-31 Reset Source is set to [0] Drive Reset, a reset according to the selected control word profile is required.
The drive-specific alarms are also reset.
If parameter 42-31 Reset Source is set to [1] Drive Safe Reset, configure [3] Safe Option Reset in parameter 8-14 Configurable Control Word
CTW.
The drive-specific alarms are not reset and the control word profile is overwritten.

6.2.2 Retrieving Safety Option Status

A subset of the safety option status can be retrieved as part of the status word. Its behavior changes based on the selected control
word profile.
Configure [91] Safe Opt. Reset. req and [90] Safe Function active in parameter 8-13 Configurable Status Word STW to:
• Indicate that a reset of the safety option is required.
• Indicate that a safe function is active.
Parameter 42-80 Safe Option Status indicates the actual status (active safe function, any requests, and error number) of the safety option
and is accessible as read-only parameter from any interface or configurable as read process data for a specific fieldbus.
Only active safe function is set in Safety Option Status.
