Error Messages Are Set After Power-On. Why?
• After the encoder has been powered, error messages can be set. Also refer to the EnDat specification. • For this reason, all errors and warnings should be cleared after powering the encoder. • If there really is an error in the encoder, the error bit will be set again during the next position request. Other information regarding errors and warnings: • It is possible to reset the error word. It is not possible to reset individual error bits (see the specification). • A given encoder does not necessarily support all alarms. The alarms supported can be read from the encoder. Alarms not supported should be masked out. • This way the control can determine whether the errors demanded by the application are even supported. • HEIDENHAIN can assign even more error messages in the future!
