this).
3. Ensure that the correct motor is running.
4. Select the SLS monitoring speed to be checked.
Notes: If you are using several SLS monitoring speeds, repeat the test for each of the monitoring
speeds.
Test each configured activation, e.g. via digital inputs and PROFIsafe.
5. Select SLS while the motor is running.
6. Check the following:
The motor speed decreases according to the selected ramp time. The motor then rotates below
•
the parameterized safely limited speed.
