4.3  Restoring Operation from Position Detector Error 
  Make sure on the error display that a position detector error is generated.    Identify the 
type of the position detector error and position data on the encoder status display, then 
perform each restoring operation. 
  4.3.1  Encoder Status Display 
  Call the encoder status screen on the teach pendant display, and make sure of the 
position data and the type of position detector error there.    The type of the position 
detector error (i.e., error status) is expressed as shown below.    The motor multi-turn 
data, home position data within one (1) full turn of motor and error status are 
displayed under the column of [MULTI], [SINGLE] and [Err-df], respectively. 
To call the encoder status screen, observe the following procedures. 
Table 4.1    Error status table 
 
Error status  Description 
0000  Signifies the normal condition. 
0100  This error occurs when a heavy vibration has been exerted on the 
robot or when the robot has been moved fast by hand while the 
power drive cable was disconnected during power OFF. 
The multi-turn data has possibly shifted. 
0200  Because axis feed was not executed after power ON, the encoder 
resolution has deteriorated.    During axis feed, the encoder 
resolution returns to normal. 
No alarm will generate. 
8000  The battery voltage has dropped. 
Replace the batteries. 
4000  The battery voltage has dropped further than the above. 
An error has possibly occurred in the multi-turn data. 
4200  Errors 4000 and 0200 have occurred at the same time. 
C200  Errors 8000, 4000 and 0200 have occurred at the same time.
