When a communication abnormality occurs between an encoder and communication circuit apparatus in a work apparatus feeding back data output from encoders for control by a control apparatus, an encoder communication circuit is used in place of the encoder to identify the location of occurrence of the abnormality. The encoder communication circuit outputs encoder data comprised position or speed data and alarm data to said control apparatus when connected to the control apparatus through a communication cable.
