Known Limitations With Design
In SF040A datadictionary (Ver 2.0.0), MotAgBufIdx input signal is removed. But it is used in the SF040A implementation(ver 2.0.0)’MotVelPer2’. This leads mismatch between DD and Design.
MotCtrlMotAgBuf and MotCtrlMotAgTiBuf are removed in data dictionary but used in the model in MotVelPer1. This leads mismatch between DD and Design.
