Variable SLS with ramp monitoring
In Variable SLS with ramp monitoring, the ramp according to which the drive
decelerates the motor to different speeds is monitored using the ramp monitoring
method (SAR1 parameters of the FSO module). Drive or SAR1 parameters define the
deceleration ramp. If the motor speed is accelerated, drive parameters define the
acceleration ramp and it is not monitored.
For configuration, see section
How to configure Variable SLS with ramp monitoring
on page
A
Variable SLS trip limits (parameter
and the scaling values set in the safety PLC)
B
Response time (depends on system configuration, see page
Ramp monitoring limits or Variable SLS trip limit (A)
Step Description
1
The Variable SLS request is received from the safety PLC (for example, 70%). The
FSO sends a request to the drive to ramp down the motor speed to the new speed limit.
2-3
After time B has elapsed, the drive starts
to ramp down the motor speed. SAR1
parameter
defines the deceleration ramp. The FSO starts to monitor the ramp
according to SAR1 parameters (
Note:
has value
0
, the drive (parameter
23.23
) defines the ramp.
Note
: If the motor speed does not follow the ramp, the FSO activates the STO function.
The FSO starts the SLS monitoring when the motor speed is in the middle of the new
SLS limit and the SLS trip limit (see also section

The new motor speed has been reached. The Variable SLS active indication
(parameter
