Requirements

To use the safety sub-functions, certain process values must be available.

• The "speed" and "acceleration" process values must be calculated for the SS1‑r, SS2‑r, SLS, SSM, SSR, SLI, SLP safety sub-functions and for the SBT brake test diagnostic function.
• The "Position" process value is used for the SOS, SDI, SLI, SLP and SCA safety sub-functions.
• The SLP and SCA safety sub-functions can only be used after the encoders involved have been referenced.
• All the limit speeds of the safety sub-functions must lie between the minimum speed and the maximum speed.

If a safety sub-function is selected without an appropriately configured process value (or other requirements), the MOVISAFE^® CSA31A safety option reports a fault. With the CSS..A safety option, the required process values are created by selecting the encoder.

For further information on parameterization of the process value generation, refer to chapter Encoder evaluation of the CSA31A safety option.

Proceed in the following order:

1. Configure the drive train in the inverter with all the encoders involved and the user units.
2. Open the "Assist CS.." parameterization tool and log in. The user units configured in the drive train are added to the "Assist CS.." parameterization tool.
3. Apply the encoder parameters to the safe configuration.
4. Also follow steps 4 – 7 for the CSA31A safety option.
5. If necessary, further configure the individual encoder type and encoder parameters.
6. Configure the application type and the function assignment.
7. Configure the involved encoders (encoder operating modes).
8. Configure safe referencing, if required.
9. Configure the required safety sub-functions.
10. The safety sub-functions can be activated via parameterization, safe digital inputs F-DI, or safe process data. Activation via safe digital inputs F-DI and safe process data is performed with logic "0".
