Title:
SOLENOID CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/024033
Kind Code:
A1
Abstract:
Provided is a solenoid control device that can accurately determine whether a movable part is in an adsorbed state of being adsorbed on a part to be adsorbed onto, on the basis of energization control of a coil.　The solenoid control device (10) comprises a control unit (43) that performs a first control and a second control with respect to an energization circuit (45). The first control is a control for delivering, to the coil (31), a drive current of a magnitude such that a movable part (36) in an adsorbed state is spaced apart from an opposing part (33). The second control is a control for delivering, to the coil (31), a current of a magnitude such that the movable part (36) in the adsorbed state is not spaced apart from the opposing part (33) and the movable part (36) not in the adsorbed state is displaced. The control unit (43) determines whether the movable part (36) is in the adsorbed state on the basis of the state of displacement of the movable part (36) when the second control has been performed.
