If the drive senses that the serial communi-cation to the encoder has stopped, it will trigger an error. If the encoder isreplaced or disconnected the drive will also trigger an error warning thatthe encoder was potentially changed. The drive will display the errormeesage E.ENCC and no further operation is possible. To clear thismeasage, it is necessary to go to parameter LF.26, press "Func" andthen press "Enter". This acknowledges that the encoder was changedor manipulated. If the encoder was infact physically replaced, it will benecesary to resynchronize the encoder to the motor pole pair beforeoperating the elevator, see section 5.11.1. Signals Formatof the analog chanels1 wave cycle per increment For a 1024 ppr encoder this is equal to360° /1024 = 0.352° mechanical revs.
