Title:
サーボモータ制御システム用の遅れ安全制動装置
Document Type and Number:
Japanese Patent JP3638285
Kind Code:
B2
Abstract:
A servomotor control system is set forth that assists in overcoming the problem of servomotor shut down during a failure of the programmable control system and/or servo-amplifier. The presently disclosed servomotor control system includes a programmable control system having one or more output signals connected to control a servo-amplifier. The system further includes a servomotor that is connected for control by the servo-amplifier. A safety switch is connected for detection by the programmable control system, the programmable control system controlling the servo-amplifier to brake the servomotor upon detection of the actuation of the safety switch. A delayed braking apparatus is disposed between the servo-amplifier and the servomotor. The delayed braking mechanism is also connected to detect the actuation of the safety switch, and acts to brake the servomotor after a predetermined time period from the detection of such actuation has lapsed.
