MC_ExtSetPointGenDisable
The external setpoint generator of an axis can be switched off with the function block MC_ExtSetPointGenDisable. The axis then no longer adopts the set value specifications from its cyclic axis interface (Axis.PlcToNc.ExtSetPos, ExtSetVelo, ExtSetAcc and ExtSetDirection)
An external setpoint generator is usually a PLC function block that calculates cyclic set values for an axis and can therefore substitute the internal setpoint generator in an NC axis.

Error : BOOL;
ErrorID : UDINT;
Enabled : BOOL;
END_VARName | Type | Description |
|---|---|---|
Done | BOOL | TRUE if the command was executed successfully. |
Busy | BOOL | TRUE as soon as the function block is active. FALSE if it is in the default state. |
Error | BOOL | TRUE, if an error occurs. |
ErrorID | UDINT | If the error output is set, this parameter supplies the error number. |
Enabled | BOOL | Shows the current state of the external setpoint generator, regardless of the function execution. |
