Conditions
A safe input must be parameterised and interconnected as an operation mode selector.
Select the operating mode for the LOW level (C15202) depending on the application. Only
one operation mode selector can be connected and parameterised. The OMS bit of the
safety bus must be deactivated (C15113).
Special operation can also be selected via the safety bus (C15113) with the OMS bit if no
safe input has been selected as an operation mode selector. In this case, at least one stop
function must be parameterised via the safety bus to ensure that the drive system is safely
switched−off if the bus should be interrupted. Furthermore, parameter C15202 must be set
to "Normal operation".
The plausibility check rejects ambiguous settings until they are parameterised correctly.
Note!
The "free traversing" setting for the special operation (C15201) motion
function must be suitable for the application!
Danger!
Dangerous situations may occur during automatic or special operation
Depending on the application, automatic or special operation may bring about
hazardous situations.
Possible consequences:
ƒ
Injury to persons
ƒ
Damage to material assets
Protective measures:
ƒ
Must be observed in particular when setting the operating mode for the
LOW level at the SD−Inx.
ƒ
Observe the notes provided in the attached application examples.
Tip!
If SLSx has been parameterised as the motion function during special
operation, a change to the acceptance operation is not possible until the
reduced speed is monitored and maintained (SLSx monitored).
