SF_end_ack_req
Safety function ending acknowledgement requested = 1,
no acknowledgement requested = 0.
Acknowledgement can be done via PROFIsafe.
Note:
These values are indicative only and shall not be
used for safety-related decisions about safety function
states (there are other ways to safely determine the state
of a function, for example, using SS1 to check octet 0 bit 4
and then octet 5 bit 4: if safe state, then SS1 is
completed).
1
SF_end_ack_req_lo
cal
Local safety function ending acknowledgement
requested = 1, no acknowledgement requested = 0.
Acknowledgement can only be done locally via the FSO
I/O if SF_end_ack_req is 0.
Note:
These values are indicative only and shall not be
used for safety-related decisions about safety function
states (there are other ways to safely determine the state
of a function, for example, using SS1 to check octet 0 bit 4
and then octet 5 bit 4: if safe state, then SS1 is
completed).
2
STO_control_active
The drive STO circuit is open.
Note
: The motor may still be rotating.
3
Speed_value_valid
Is the speed value valid (= 1) or not (= 0).
The speed value is defined in octets 6 and 7.
Note:
Octet 2 bit 0 indicates the speed source and octet 5
bit 3 indicates the validity of the indicated speed source.
4
FSO_state
Safe state = 1
Operational state = 0
5
FSO_mode.0
6
FSO_mode.1
7
Modulating
The drive is modulating = 1
It is unknown if the drive is modulating or not = 0
Note:
It can only be ensured by activating drive STO that
drive is
not
modulating. Drive STO can be activated, eg,
with FSO STO or POUS function.
6
Safe_speed_MSB
The current motor speed value from FSO (LSB).
7
Safe_speed_LSB
The current motor speed value from FSO (MSB).
*)
The safety PLC must ignore the value of the reserved bits. This ensures the compatibility
with future versions of the PROFIsafe profile where the reserved bits may be used.
