MC_CamRemove
This function block removes a cam table coupling from a slave.
As a cam table can only be used once in a coupled slave, the master information is not needed.
However, the cam table must be in use when this function block is executed and when the activation condition is met, otherwise an error is triggered.
If there is no active coupling left and there are no pending commands to add couplings, the camming synchronization ends by itself and axis state changes to Standstill.

Possible error codes
For this function block, the following values, among others, are possible for the ErrorId output:
Error(Hex) | Error(Dec) | Error type | Description |
|---|---|---|---|
0x8145 | 33093 | Function Block | Mapping of cyclic interface between NC and PLC is missing (e.g., AXIS_REF, AXES_GROUP_REF, ...). A reference used by the function block (e.g., to an axis, group, mover or other motion object) is not linked to the corresponding NC object, or its cyclic mapping is incomplete. |
0x8169 | 33129 | Function Block | Master axis does not exist or cannot be used. The axis passed as master does not exist or has no cyclic mapping and therefore cannot be used as master (e.g., for camming or gearing). |
0x81af | 33199 | Function Block | Invalid object or object reference passed to function block. An invalid or missing object reference was passed to the function block (e.g., missing CamObject reference on MC_CamIn, MC_CamTableSelect or MC_CamScaling). |
0x81b0 | 33200 | Function Block | Object not allowed (e.g., object is already in use). The supplied object is not allowed in the current context (e.g., source and target are identical in CopyFrom(), the object is already used by another axis). |
0x81b1 | 33201 | Function Block | Invalid size passed to function block (e.g., invalid array size or invalid number of elements). An invalid size was passed to the function block (e.g., CamRef.NumberOfPoints less than two on MC_CamTableSelect). |
0x81b2 | 33202 | Function Block | The given cam activation settings are invalid. The activation settings of the cam table (e.g., ActivationMode and ActivationPosition) are invalid or inconsistent. |
0x81b3 | 33203 | Function Block | The given cam scaling is invalid. The supplied cam table scaling parameters are invalid (e.g., scale factor of zero, or master offset mode Auto which is not supported in the executed operation). |
0x81b4 | 33204 | Function Block | The given cam data point is invalid. At least one data point of the cam table is invalid (e.g., the first or last point is being ignored). |
0x81c2 | 33218 | State | A queued cam command could not be transitioned from queued to active. An error occurred while transitioning a queued cam command (e.g. MC_CamIn, MC_CamAdd, MC_CamExchange, MC_CamScaling or MC_CamRemove) to the active state. This typically happens when the camming state changed between queuing and activation, for example because the referenced cam table is already coupled or no longer coupled, or because the setpoint or activation time could not be computed. |
