Error BOOL Calculation of the influenced variable "Value" completed with error, output variable ErrorIdent is valid ErrorID ERROR_CODE Short error description ErrorIdent ERROR_STRUCT Detailed description of the diagnostics in case of an error Changing BOOL Calculation of the influenced variable takes place. Influenced variable "Value" is valid HighLimitAck BOOL Maximum output value of the influenced variable reached LowLimitAck BOOL Minimum output value of the influenced variable reached VAR_IN_OUT Value REAL Influenced variable Fig. 1-62: Interface of FB MX_ContinuousAdjustType01 Signal-Time Diagram Fig. 1-63: Continuous Parameter Adjustment Functional Description The adjustment of the influenced variable, „Value“ may take place in positive or negative direction. The limits set a valid range for adjusting the variable. Specifying a modulo value allows the adjustment to be withing an axis‘ frame for reference. Predefining increments and increments per second determines the alteration velocity of the influenced variable. It is possible to write a given value („PresetValue“), inside the valid operating range, directly to the influenced variable. After activation, with „Enable“, the influenced variable can be changed via inputs „Inc“ (positive direction) and „Dec“ (negative direction). While input „Inc“or Dec is set, the influenced variable is continuously increased (or decreased) with the given velocity. (StepsPerSecond * StepWidth). At initialization, ensure the inputs „ModuloValue“, „HighLimit“ and „LowLimit“, contain valid values. By determining weighting factors („AdjWeightFactors[]“) and the corresponding time intervals („AdjTimeIntervals[]“) it is possible to make time-dependent velocity modifications. The weighting factors and time intervals must also be set on the inputs „StepsPerSecond“ and „StepWidth“. Depending on the actual time interval, the alteration velocity is then multilpied with the appropriate weighting factor. The figure below shows the behavior of the block with an example configuration: The input factors of „AdjTimeIntervals“ ([T1; T2; T3; T4]) are specified in seconds. T5 specifies the period after completion of time interval T4 when the adjustment procedure aborts. The input factors of „AdjWeightFactors“ ([0,5; 1; 1,5; 2; 4]) determine the weighting of the alteration velocity. The last value of „AdjWeightFactors [5]“ is assigned to time interval T5.

1-48 MLD-S Technology Library Rexroth MLD-S Tech-FB Library Fig. 1-64: WeightedAdjustment Note: When a time interval = 0, so the next weighting factor is used until the adjustment process aborts. Example: If AdjTimeIntervals[2] = 0, then the weighting factor of AdjWeightFactors[3] is used until abortion. To determine the correct time interval of the weighting factors, the expired time is reset with each new starting adjustment process. If inputs „AdjWeightFactors“ and „AdjTimeIntervals“ are not set, a continuous adjustment with the given alteration velocity specified with „StepsPerSecond“ and „StepWidth“ occurs. Note: Values in “AdjTimeIntervals“ must only contain positive values. Weighting factors can be positive or negative. The influenced variable can only be set to the specified preset value if it is within the valid range between „HighLimit“ and „LowLimit“. Output „InOperation“ signals that the block is in use, but an adjustment is not active. " Changing" indicates an error-free adjustment and the value of the adjusted variable „Value“ is valid. “Error“ indicates that an error occurred during the adjustment process. Details are indicated in the „ErrorIdent“ structure.
