MC_ExtSetPointGenDisable

MC_ExtSetPointGenDisable 1:

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.

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.
