TROUBLESHOOTING

TROUBLESHOOTING Overview 81.1  OverviewThis chapter describes how to identify troubles in two levels: unit level repair and 
component level repair. Refer to the flowchart in this chapter to identify the defective 
unit and perform component level repair if necessary. This chapter also explains motor 
coil resistance, sensor specification and error indication.
Table 1-1.  Troubleshooting FlowchartSince CR Motor and APG Motor are DC Motors, the resistance among the electric 
poles varies. Therefore, judge if it is normal or abnormal based on if there is no 
operation of the motor or not; the resistance values cannot be used to judge the 
abnormality. However, it is difficult to judge accurately, if it is not clear, replace the 
motor.
