Validation

Validation is done on transferred parameters using CRC. Parameters transferred with FSoE (when FSoE parametrization is used) do not require user validation.

More information referring to parameter download (see "Downloading Safety Parameter Packages").

Validation of SafeID

If the SafeID is not flagged as validated when booting, you will get the message: "SafeID not validated" . Then do the following:

  • Compare the displayed SafeID with the paperwork.
  • If the SafeID is correct, press button B2 twice within 10 seconds to validate. If you do not press B2, the drive remains in the safe state.

Validation of the SafeID is performed through FSoE

  • if FSoE parameterization is used and
  • if the SafeID is not validated yet and
  • if the SafeID matched the safe address defined in the safe PLC.

Validation of Safety Parameters

The parameter CRC is equal to the system CRC. The character string of the SafeID is concatenated with the character string of the CRC.

The purpose of validation is to ensure that all safety parameters as a group are suitable for the application.

Example for invalid parameters: The parameters are valid for an elevator drive, but they are not for a paper machine drive.

The person responsible for validation must document decisions. Therefore the safety related system stores information about the user (user name, date of validation).

  • The user checks the System CRC. This value is read from the drive (see parameter value SAFE.CRC). This may require the user to sign a document about the correct parameters having been entered.
  • The user must check if all drives have been programmed correctly.

Validation of Safe I/O Installation

The person conducting the validation must be independent of the Safety Function Design. See ISO 13849-2:2012, 4.1 Validation principles.

Validation Report

To assist commissioning and documentation, WorkBench offers to print a “Safe Motion Validation Report” suiting the safety parameter configuration. Select the corresponding safety parameter package (1). To view the validation report, click on “View” (2) directly or “View Validation Report” (3).

The “Safe Motion Validation Plan” lists all configured functions and their parameterized values (expected behavior). The validators can use it as guidance to verify all parameters and functions.
