The compatibility only applies to the safety functions and features that are used. It is not necessary to take into account the safety
functions and features that are not used. See Table 50.
Table 50: The Compatibility of Parameters with PROFIdrive on PROFIsafe
PROFIdrive on PROFIsafe assumes that the fault log and the safety fault log are
controlled separately. Only the safety system should be permitted to reset the
safety faults.
The acknowledgment of safety functions from non-safe source not allowed.
Acknowledgment
mode (all safety
functions)
Automatic mode assumed in PROFIdrive on PROFIsafe.
Safety Telegram 31 does not have control bit for SSM. Always active assumed.
Minimum speed monitoring not considered in PROFIdrive on PROFIsafe. Other
values than zero cause also slow speeds to activate the SSM output of the
drive, instead of just higher than SSM Max Limit speeds.
1
The option is not compatible.
2
The option is compatible.
3
The option can be used, but it is not mentioned in the PROFIdrive on PROFIsafe amendment.
PROFIdrive on PROFIsafe defines 4 SLS limits, but the Advanced safety option board only supports 3 SLS limits. The fourth limit
selection is not used. An SLS request with the fourth limit selection is invalid and will cause a fault. See chapter
7.1.6.7 Safety Control
Word 2 (S_STW2).
The safety functions in the Advanced safety option board can be parameterized in more detail than what is described in the PROFI-
drive on PROFIsafe amendment. If you use such details, take them into account with the F-Host.
7.1.6.2 PROFIsafe over PROFIBUS
When using PROFIBUS, the PROFIsafe data must always be in Slot 1. In the Advanced safety option board, only one Safety Telegram
is permitted to be selected at once.
For information on the supported telegram combinations, see VACON

The F-I/O Data consists of PROFIsafe user data, which consists of PROFIdrive Safety Signals. The Safety Signals inside the F-I/O Data
together with the PROFIsafe trailer (see 7.1.4 The PROFIsafe Frame) form the PROFIdrive Safety Telegram.
