①
– The delay time is only displayed if you selected "acceleration monitoring" at the
start of commissioning.
The selected delay time must be greater than the time that the motor requires when
SLS is selected for braking with maximum load from the maximum speed down to the
lowest SLS level.
②
– Setpoint speed limit as a % of the monitoring threshold.
This parameter defines the upper speed limit when SLS is active.
③
– Monitoring threshold.
Enter the load-side speed to be monitored. The inverter calculates the maximum
motor speed on the basis of this parameter and the gear ratio.
④
– Reaction when the monitoring responds.
