Braking below the SLS limit
value
Motor/converter response
•
The converter detects the selection of SLS.
•
The converter detects when the SLS2 limit value is selected.
•
The converter starts the SLS delay time (p9551).
•
The motor follows the setpoint of the higher-level control and
brakes.
2)
•
The actual speed must remain below the SLS2 limit value until
the SLS delay time has elapsed.
•
Monitoring of the SLS2 limit value (p9531[1)] is effective once
the SLS delay time (p9551) has elapsed.
•
The converter signals the status "SLS active" (r9722.4) and the
active SLS level (r9722.9 = 1, r9722.10 = 0).
•
If the motor speed violates the SLS2 limit value, the converter
initiates the set stop response p9563[1].
•
The converter detects when the SLS1 limit value is selected.
•
The converter starts the SLS delay time (p9551). The SLS2 limit
value remains while the SLS delay time is active.
•
The motor follows the setpoint of the higher-level control and
brakes.
2)
•
The actual speed must remain below the SLS1 limit value until
the SLS delay time has elapsed.
