1.1
Overview
This 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.
Figure 1-1.
Troubleshooting Flowchart
Since "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 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.
