Start-up and acceptance test 27
Make sure that the motors stay at zero speed and the inverter units indicate POUS as defined in
section
on page
Note that there can be several POUS groups in a multidrives system. Make sure that only the desired
inverter units indicate POUS.
Make sure that you cannot start the inverter units and motors from any control location: Switch the
external start signal off and on (in the external control mode) or push the start key of the control panel
(in the local control mode). The LOC and REM buttons of the control panel or the Drive composer PC
tool switch between the local and external controls.
Drives with R8i inverter modules: Make sure that “STO hardware failure” (5090) is not generated.
Deactivate the POUS function by switching on the POUS switch. Make sure that the inverter units do
not restart directly after deactivation.
Switch off the inverter units start signals (only in external control mode).
If the inverter units generate a fault message, reset the inverter units.
Restart the inverter units and motors and make sure that they operate normally.
Repeat the acceptance test for each POUS group.
If you made any changes in the FSO parameters, save the FSO safety file (button
Save safety file
in
the Drive composer pro PC tool).
Fill in and sign the acceptance test report which verifies that the safety function is safe and accepted
to operation.
