Upper limit position and lower limit position setting device and method in the initial setting mode of the shutter device

摘要

PROBLEM TO BE SOLVED: To determine a direction of rotation of an opening/closing unit at the time of upper limit position/lower limit position setting in an initial setting mode.;SOLUTION: An upper limit position/lower limit position setting device includes: a first switch for making a motor of an opening/closing unit rotate in a first direction; and a second switch for making the motor of the opening/closing unit rotate in a second direction opposite to the first direction. When a shutter curtain is raised by input of the first switch, an upper limit position is set when the shutter curtain is raised up to an upper limit. When the shutter curtain is raised by input of the second switch, the upper limit position is set when the shutter curtain is raised up to the upper limit and a preset direction of rotation of the motor is switched to an opposite direction at the time of the upper limit position setting, the shutter curtain is lowered by input of the second switch after the upper limit position setting, and a lower limit position is set when the shutter curtain is lowered to a lower limit.;COPYRIGHT: (C)2013,JPO&INPIT
