<P>PROBLEM TO BE SOLVED: To provide a crossing gate capable of confirming a normal state and an abnormal state during a blocking operation in an installation site, focusing on the abnormal state. <P>SOLUTION: A servo motor drive section 3 includes a control part 31, a setting part 33, and display parts 35 and 37. The control part 31 controls at least a current supplied to a servo motor 1, a gate lowering operation time of the servo motor 1, and a stop position of the servo motor 1. The setting part 33 sets a limit value of the current, gate lowering operation time, and stop position. The display parts 35, 37 display the current, gate lowering operation time, stop position, and their normal/abnormal states, and are arranged on a case so that their display contents can be visually recognized. <P>COPYRIGHT: (C)2013,JPO&INPIT |
