Abstract

PURPOSE:To enable a robot to escape automatically from a stop limit area by invalidating a detecting signal of a stop limit area detecting switch and actuating an original point positioning means when the robot enters the stop limit area. CONSTITUTION:When the Z axis enters the stop limit area, any one of the switches SW1, SW2 is turned on. Since the switch SW2 is also turned on when the switch SW1 is turned on, a control part can determine which stop limit area out of right and left ones is concerned. When any one of the switches SW1, SW2 is turned on, the control part stops the movement of the Z axis. When a stop limit cancelling key LS and an original point positioning key ORG on an operation panel are depressed, stop limit information is not inputted and original point positioning starts. Consequently, the operability is improved and malfunctions can be prevented.

Therefore, conventionally, movement control (10 degrees) operation is used to move left and right on the Y axis 1IJj (SνT, lJ direction and S
W 3 directions) During operation 6 or during automatic operation, the Z axis enters the switch SW ] (or 5W3) (dog 1)
, when overtravel (entering the stop limit, 1 area), the control section cuts off the power source (servo motor power supply r, h) and manually switches switch SW2 and switch SW3.
In the meantime, move the Z-axis, escape from the immediate stop area, and restart iti.
Turn on the power to the control unit, pass through the origin position f'', and move to 7'CQ. Also, as a way to escape from the stop fox area, operate the key to disable switch SW1 and the movement key in the right direction at the same time, After the Z-axis is moved out of the stop limit area, it is also possible to lift the Z-axis to the origin using the reference level lIM.
