Function test "Safely-Limited Speed" (SLS)

This test comprises the following steps:

Table A-6 "Safely-Limited Speed" function (SLS)

No. Description Status

1. Initial state

• Drive is "Ready to Run" (P0010 = 0)

• No safety faults and alarms

• r9772.4 = r9772.5 = 0 (SLS de-selected and inactive)

2. Operate the drive (if the machine permits it, at a higher speed than the

parameterized safely-limited speed)

3. Check that the expected drive operates

4. Select SLS while issuing the traversing command

5. Check the following:

• r9772.4 = 1 (SLS selected)

• Drive speed decreases corresponding to the selected ramp time or SLS

mode (if required, use an oscilloscope)

• After the parameterized safely-limited speed has been fallen below, the

speed remains below this limit

– In SLS mode 1 à correct, must be no fault

– In SLS mode 0 à LSTO (safety fault at ramping end)

– In SLS mode 2 à LSTO (immediately)

• r9772.5 = 1 (SLS active)

6. De-select SLS

7. Check the following:

• No safety faults

• r9772.4 = r9772.5 = 0 (SLS de-selected and inactive)

8. Check that the expected drive operates if so the following is tested:

• The wiring between the control unit and power module is correct

• Correct assignment, drive No. – inverter power module – motor

• Correct functioning of the hardware

• Correct wiring of the shutdown paths

• Correct parameterization of the SLS function
