The System Identification VIs can return the following error codes. Refer to the KnowledgeBase for more information about correcting errors in LabVIEW.

Code Description
−41353 Failed to get a valid model type. Specify different orders and try again. If this error occurs again, try other estimation methods instead.
−41352 Invalid input signals. Ensure the input signals are step signals and step response signals.
−41351 The input signal length is too short for estimation. Ensure the length is more than 20. If the input signal contains an initial part, ensure the length of the initial part is more than five.
−41342 The system model must be a discrete model.
−41341 The system model must be a continuous model.
−41333 The orders of the estimated transfer function model are not consistent with the orders you specified. You must adjust the tolerance setting to reduce estimated model orders.

−41331 The System Identification Toolkit does not convert the static gain into the transfer function gain.
−41329 The number of states is too large. Either increase the length of the input data or decrease the number of states.

−41283 The order of the B coefficients in the linear model must be greater than zero.
−41282 The order of the A coefficients in the linear model must be greater than or equal to zero.
−41281 The order of the A coefficients in the linear model must be greater than zero.
−41264 The model coefficients are invalid.
−41263 The System Identification Toolkit cannot retrieve the data in system model because the model type you wire in is incompatible with the system model requirements.
−41262 The model orders are inconsistent with the dimensions of the model coefficients.
−41261 The system model is undefined.
−41235 The lower limit you specified for the parameters is invalid.
−41234 The values you specified do not match the upper and lower limits.

−41225 The length of the response signal that the user-defined VI generates is different from the length of the stimulus signal.
−41224 The length of FRF weight must be equal to the lengths of the components of FRF magnitude and FRF phase

−41215 The confidence factor must be greater than zero.
−41214 The selected channel is out of range.

−41211 The reference value must be greater than zero.
−41210 The reference matrix must be square matrix. The dimensions of the reference matrix do not match the number of coefficients of the system model.

−41207 The number of noise channels does not match the system model requirements.

−41203 The values of piecewise points must be unique and in ascending order.
−41202 The decimation factor must be greater than one.
−41201 The signal length is too small for computation, or the stimulus and response signals are not of the same length.
41201 At least one of the signal inputs is empty. Most System Identification VIs have stimulus signal and response signal inputs. Some VIs require these two inputs to have the same length. Other VIs, such as the Data Preprocessing VIs, allow the stimulus signal or the response signal to be ignored. If a VI does not require the two inputs to have the same length, this warning occurs when the stimulus signal or the response signal is empty.
41202 The denominator order is too high for the transfer function model, which might result in an inaccurate estimation.
41203 The numerator order is too high for the transfer function model, which might result in an inaccurate estimation.
