FLOW VALVE CONTROL DEVICE AND FLOW VALVE MANUFACTURING METHOD |
| 摘要 |
PROBLEM TO BE SOLVED: To solve the problem wherein it is impossible to process accurate initialization of a stepper motor type flow valve. SOLUTION: A stepper motor is driven with a drive signal of frequency prohibiting step-out in an unloaded condition but allowing step-out when abutting on the other end of a valve stem. After the step-out of the stepper motor, initialization is processed. COPYRIGHT: (C)2005,JPO&NCIPI |
