Approvals
When one MCP is switched over to another, any active feed or axis enables will be retained.
Note
Keys actuated at the moment of switchover remain operative until the new MCP is activated
(by the HMI, which is subsequently activated). The override settings for feedrate and spindle
also remain valid. To deactivate actuated keys, the input image of the machine control
signals must be switched to non-actuated signal level on a falling edge of DB10.DBX104.0.
The override settings should remain unchanged.
Measures for deactivating keys must be implemented in the PLC user program
(see below: Example of override switchover).
The call is permitted only in cyclic program OB1.
