Abstract
There has been a problem that in the operation of a teach pendant having two enable devices (3-position switches) on the right and left sides, shifting it from one hand to the other results in prohibition of operation. In that operation is made possible until a predetermined time elapses even if the 3-position switches are operated by both hands in shifting the teach pendant from one hand to the other, shifting it from one hand to the other is allowed, making continuous operation of the teach pendant possible, while ensuring security in that when the time of operation with both hands exceeds the predetermined time, operation is inhibited.
Claims6
A control method for a teach pendant,
- the teach pendant including:
- two three-position switches respectively having three operating positions of first operating positions, second operating positions and third operating positions in accordance with pressing-down strokes,
- the three-position switch having:
- a detecting unit for detecting the first operating position and the third operating position to permit or inhibit the operation of a device in accordance with the operating positions,
- the control method comprising:
- a step of inhibiting the operation of the device, when both the three-position switches are located at the second operating positions for a time exceeding a prescribed time.
A control device for a teach pendant,
- the teach pendant including:
- two three-position switches respectively having three operating positions of first operating positions, second operating positions and third operating positions in accordance with pressing-down strokes,
- the three-position switch including:
- a signal processing circuit having a detecting contact for detecting the first operating position and the third operating position to permit or inhibit the operation of a device in accordance with the operating positions, wherein
- the signal processing circuit has detecting contact signals of the three-position switches as inputs to establish an inhibiting state of the operation of the device when both the three-position switches are located at the second operating position for a time exceeding a prescribed time, and to allow both the three-position switches to be located at the first operating positions to cancel the inhibiting state of the operation of the device.
