5.6.4 Safe operation mode selector
Operation Mode Selector / OMS
The function provides a special operation of the drive. In the special operation the drive is
stopped (status 2). The drive can be traversed in the special operation via an enable switch
(status 3).
For the stop status in the special operation, the STO or SS1 functions can be parameterised.
For motion functions in the special operation, the free movement can be parameterised.
The parameterised monitoring function will be automatically activated with the transition
to the special operation.
The special operation enables an override of the simple STO and SS1 stop functions by the
enable switch.
An active emergency stop function is also executed in special operation.
The special operation can also be selected via the safety bus by the F−PLC, unless a safe
input is parameterised as operation mode selector.
The return to normal operation is only possible in the stop status. Since the drive is stopped
in status 2, the AIS acknowledgement is required for restart. The parameters for the restart
STO/SS1 are used.
)
Note!
When returning to normal operation, the automatic restart is not permissible.
If "automatic restart" is parameterised, this can be prevented by special
measures, e.g. programming in the higher−level control.
)
Note!
The "safe enable switch" function serves to directly cancel/complete the
stopping times assigned to the stop functions.
)
Note!
If an error (e.g. a discrepancy error) occurs at a safe input to which the OMS
function has been assigned, normal operation will be selected. This
corresponds to the OFF state. The "S_Error" LED is lit and STO is not activated.
The special operation can only be selected again when the error has been
eliminated and acknowledged.
