APPENDIX 2.2 Minor errors 
These errors are detected in the PLC program or Motion program, and the error codes 
of 1 to 999 are used. 
Minor errors include the setting data errors, starting errors, positioning control errors,  
speed change/torque control value change errors and Motion program execution 
errors. 
(1)   Setting data errors (1 to 99) 
These errors occur when the data set in the parameters for positioning control is 
not correct. 
The error codes, causes, processing and corrective actions are shown in Table 
2.3.
