100 Safety functions
Step Description
1
The SLS request is received. The motor speed is above the SLS limit positive (B).
2
After time C has elapsed, the drive starts to ramp down the motor speed. The SAR1
parameter
defines the deceleration ramp until the speed reaches the SLS limit
positive (B). The FSO starts the SAR1 ramp monitoring (parameters
).
Note:
If parameter
has value
0
, the drive (parameter
23.23
) defines the ramp.
The FSO starts the SLS monitoring when the motor speed is in the middle of the SLS
limit and the SLS trip limit (see also section
How to fine-tune when monitoring is started
on page
), and stops the SAR1 monitoring. The SLS indication (parameter
,
) goes on.
2b
If the motor speed does not follow the ramp monitoring limits, the FSO activates the
STO function. See section
on page
for more information on
how to configure the STO function.
3
The motor speed reaches the SLS limit positive (B).
3-5
The drive limits the motor speed, but if the motor speed still reaches the SLS trip limit
positive, the FSO activates the SSE function. For more information, see section
on page
.
4
The SLS request is removed, but the SLS monitoring is still on (acknowledgement
method is manual or from a safety PLC).
Note
: If automatic acknowledgement is used, the SLS monitoring is also ended.
5
The SLS function is acknowledged and the FSO stops the SLS monitoring. The SLS
indication (parameter
,
) goes off.
