METHOD AND DEVICE FOR CONTROLLING GALVANOSCANNER |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To prevent deterioration in positioning precision and a coil burning due to motor coil heat generation of a galvanoscanner while minimizing a decrease in throughput. <P>SOLUTION: Based on the state of variation of a driving signal, a state wherein an error due to the heat generation of a motor coil is about to occur is detected and the driving state is changed to suppress the heat generation of the motor coil. <P>COPYRIGHT: (C)2004,JPO</p> |
