FB_Brake - General Information

Overview

Type:	Function block
Available as of:	V1.0.7.0
Inherits from:	-
Implements:	-
Versions:	Current version

Task

Releasing the motor brake.

Description

A positive edge at the i_xRelease input releases the motor brake.

A negative edge at the i_xRelease input allows the motor brake to engage.

NOTE: POU changes cycle time monitoring!

The POU relatively increases the settings of the cycle time monitoring in the enabled state.

The POU independently resets this relative increase when no longer required.

Hereto, the POU must be called-up correctly.

Interface

Input	Data type	Description
i_xEnable	BOOL	A rising edge FALSE -> TRUE activates the POU, a falling edge TRUE -> FALSE deactivates the POU. A deactivated POU does not execute any actions.
i_xRelease	BOOL	TRUE: the brake will be released. FALSE: the brake will be closed.
i_ifDrive	IF_Drive	Input for the axis that shall be controlled.

AsyncInitNotFinished

Enumeration name:	AsyncInitNotFinished
Enumeration value:	290
Description:	Init has not been completed yet.

Issue	Cause	Solution
-	Init() method has not yet been completed.	Call up the Init() before you call up Start() for the first time. After you have called up the Init, wait until Init has been executed successfully. (Init.q_xDone = TRUE)

Issue

Cause

Solution

Init() method has not yet been completed.

Call up the Init() before you call up Start() for the first time.

After you have called up the Init, wait until Init has been executed successfully. (Init.q_xDone = TRUE)

AsyncInvalid

Enumeration name:	AsyncInvalid
Enumeration value:	288
Description:	The value of IF_Async is invalid.

Issue	Cause	Solution
-	No valid value has been transferred at the i_ifAsync input.	Verify the value at the i_ifAsync input for <> 0.

BrakeStateChangedNotInTime

Enumeration name:	BrakeStateChangedNotInTime
Enumeration value:	278
Description:	The BrakeState did not change in time.

Issue	Cause	Solution
-	An unintended error has been detected while releasing the brake.	Please inform your Schneider Electric representative about this detected error.

ColdResetOfControllerNecessary

Enumeration name:	ColdResetOfControllerNecessary
Enumeration value:	297
Description:	A cold start of the controller is required

Issue	Cause	Solution
-	Gc_udiNumOfAsyncTasks has been changed.	A cold start of the controller and a call up of Init() is required.

Disabled

Enumeration name:	Disabled
Enumeration value:	9
Description:	The POU is disabled.

The function block is disabled and executes no actions whatsoever. i_xEnable and q_xActive are set to FALSE

DriveInvalid

Enumeration name:	DriveInvalid
Enumeration value:	3
Description:	The connected drive is invalid.

Issue	Cause	Solution
-	At the input i_ifDrive, no drive was applied.	At the input i_ifDrive, a valid drive must be transferred.

Issue

Cause

Solution

At the input i_ifDrive, no drive was applied.

At the input i_ifDrive, a valid drive must be transferred.

The connected drive does not support all required functionalities.
