50 Parameter settings
In SLS with time monitoring, the drive (parameter 23.13 Deceleration time 1 or 23.15
Deceleration time 2) always defines the deceleration ramp.
In SLS with ramp monitoring, the drive uses either the ramp settings in the FSO module or
the drive. If FSO parameter 200.112 SAR1 ramp time to zero is set to 0, the drive (parameter
23.23 Emergency stop time) defines the deceleration ramp. In this case, the FSO module
monitors the actual deceleration ramp using SAR1 parameters.
After the SLS function is deactivated, the drive returns to normal operation and starts to
follow its ordinary speed reference. The drive accelerates the motor to the desired speed
along its acceleration ramp. Drive parameters define the acceleration ramp and it is not
monitored.
For the parameter settings in the drive, see the firmware manual.
