MC_CamRemove

MC_CamRemove 1:

MC_CamRemove removes a cam plate from a multi-cam coupling. The cam plate coupling is initially created with MC_CamIn_V2.

Alternatively, a cam plate can be removed with MC_CamIn_V2.

The block can be used from a runtime version TwinCAT 2.11 R2

Important :

ActivationMode (time and/or position from which the operation takes place)

Inputs

VAR_INPUT 
    Execute : BOOL;
 ActivationMode : MC_CamActivationMode := MC_CAMACTIVATION_INSTANTANEOUS;
 ActivationPosition : LREAL;
 CamTableID : MC_CAM_ID; 
    Options : ST_CamInOptions_V2;
END_VAR

Execute	The command is executed with a rising edge at input Execute.
ActivationMode	The ActivationMode is used to specify the time and/or position at which the cam plate coupling or switchover is to take place. ActivationMode can also be specified when a slave is coupled for the first time.
ActivationPosition	Optional master position at which a cam plate is switched, depending on the ActivationMode. (not required for first coupling.) If ActivationMode MC_CAMACTIVATION_ATMASTERCAMPOS is used, the position refers to the non-scaled cam plate. If the position in the application refers to the scaled cam plate, it can be divided by the MasterScaling before the function block is called.
CamTableID	ID of the cam plate that is removed from the coupled system.
Options	not used

Outputs

VAR_OUTPUT
   Done:           BOOL;
   Busy:           BOOL; 
   Active:         BOOL; 
   CommandAborted: BOOL;
   Error:          BOOL;
   ErrorID:        UDINT;
END_VAR

Done	Becomes TRUE if the cam plate operation was completed successfully. In operations with activation position Done only becomes TRUE after the actual deactivation.
Busy	The Busy output becomes TRUE when the command is started with Execute and remains TRUE as long as the command is processed. When Busy becomes FALSE again, the function block is ready for a new command. At the same time one of the outputs InSync, CommandAborted or Error is set.
Active	Active indicates that the command is executed. Active becomes TRUE if the command was issued successfully but the operation is still queued. If the cam plate is activated depending on the ActivationMode, Active becomes FALSE and InSync is set.
CommandAborted	Becomes TRUE, if the command could not be fully executed. The axis may have become decoupled during the coupling process (simultaneous command execution).
Error	Becomes TRUE, as soon as an error occurs.
ErrorID	If the error output is set, this parameter supplies the error number.

Inputs/outputs

VAR_IN_OUT
    Master : AXIS_REF;
 Slave : AXIS_REF;
END_VAR

Master	Master axis data structure.
Slave	Axis data structure of the Slave.

The axis data structure of type AXIS_REF addresses an axis uniquely within the system. Among other parameters it contains the current axis status, including position, velocity or error status.
