FB_SoEAX5000SetMotorCtrlWord

With the function block FB_SoEAX5000SetMotorCtrlWord the ForceLock bit (Bit 0) or the ForceUnlock bit can be set in the Motor Control Word (P-0-0096) to activate or release the brake. Normally the brake is automatically controlled via the Enable of the drive.

With the ForceLock bit, the brake can be activated independently from the Enable, with the ForceUnlock bit, the brake can be released independently from the Enable. In the case of simultaneously set ForceLock and ForceUnlock, ForceLock (Brake activated) has the higher priority.

Inputs

    tTimeout     : TIME := DEFAULT_ADS_TIMEOUT;
    bForceLock   : BOOL;
    bForceUnlock : BOOL;
END_VAR

Name	Type	Description
sNetId	T_AmsNetId	String, which contains the AMS Network ID of the PC (type: T_AmsNetId).
bExecute	BOOL	The function block is enabled via a positive edge at this input.
tTimeout	TIME	Maximum time allowed for the execution of the function block.
bForceLock	BOOL	Activates the brake independently of the enable.
bForceUnlock	BOOL	Releases the brake independently of the enable.

Inputs/outputs

VAR_IN_OUT
    Axis : NCTOPLC_AXIS_REF;(* reference to NC axis *)
END_VAR

Name	Type	Description
Axis	NCTOPLC_AXIS_REF	Axis data structure of the type NCTOPLC_AXIS_REF

Outputs

VAR_OUTPUT
    bBusy        : BOOL;
    bError       : BOOL;
    iAdsErrId    : UINT;
    iSercosErrId : UINT;
END_VAR

Name	Type	Description
bBusy	BOOL	This output is set when the function block is activated, and remains set until a feedback is received.
bError	BOOL	This output is set after the bBusy output has been reset when an error occurs in the transmission of the command.
iAdsErrId	UINT	Returns the ADS error code of the last executed command when the bError output is set.
iSercosErrId	UINT	In the case of a set bError output returns the Sercos error of the last executed command.
