FUNCTION_BLOCK SMC3_BrakeControl
This function block, if supported by the drive and its SoftMotion driver, it determines the behaviour of a mechanical brake. By use of this function block in the application the brake can be closed or opened or it can be switched to automatic mode, in which the opening and closing is handled by the drive itself. The function can be used if it is not possible to use the automatic mode due to special requirements (i.e. manual move of a component) of the application where the brake must be controlled manually. The function block does not take on any further monitoring or other intelligent functions (i.e. time delayed opening of the brake).
