Function test "Safe Stop 1" (SS1)

This test comprises the following steps:

Table A-5 "Safe Stop 1" function (SS1)

No. Description Status

1. Initial state

• Drive is "Ready to Run" (P0010 = 0)

• No safety faults and alarms

• r9772.0 = r9772.1 = 0 (STO de-selected and inactive)

• r9772.2 = r9772.3 = 0 (SS1 de-selected and inactive)

2. Operate the drive

3. Check that the expected drive operates

4. Select SS1 while issuing the traversing command

5. Check the following:

• Drive speed decreases corresponding to the selected ramp time (if

required, use a stop watch)

• After the parameterized minimum speed has been fallen below, the drive

coasts-down

• The drive is braked and held by the mechanical brake if a brake is being

used

• No safety faults

• r9772.1 = 1 (STO active)

• r9772.2 = 1 (SS1 selected)

• r9772.14 = 1 if safe brake monitoring is enabled

6. De-select SS1

7. Check the following:

• No safety faults

• r9772.1 = 0 (STO inactive)

• r9772.2 = 0 (SS1 de-selected)

• r9772.14 = 0

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 assignment, STO terminals on the control unit

• Correct parameterization of the SS1 function
