Operating Instructions, 02/2019, 4BS0751-007
Check the setting of the bail switch S3 on peripheral board DI/DO:
• open: for single-circuit trip
• closed: for two-circuit trip
Connect power to the inverter.
Check parameter "P-INVERTER DATA/STO":
• "X2:20": for single-circuit trip
• "X2:20/24": for two-circuit trip
It is advantageous if you track the "Status" inverter actual value. You can either do this
in the display, if you parameterize this actual value temporarily in the 4th status line or in
the IMS, if you are connected with a PC.
If required, enter the necessary switch-on commands so that the inverter is at least in
the ready state, i.e. is in the "Status = Rdy.f.work".
The "READY" LED is lit.
(Simultaneously) open the safety circuit(s), that is/are connected as follows:
• For single-circuit trip at -X2:19/:20.
• For a two-circuit trip, additionally at –X2:24/:3
The inverter switches into the "Switch interlock" status, LED "READY" goes dark.
The "Safe torque off" "active" message is displayed.
By pressing "RESET", attempt to exit the state.
It is not permissible that the inverter exits the "Switch interlock" state.
The message "Safe torque off" "active" must remain active.
Connect the safety circuit(s) at –X2:19/:20 and possibly at –X2:24/:3.
The inverter initially stays in the "Switch interlock" state; however, the display changes
to "!! OFF2 !!" After STO act.".
