Page 77
CHAPTER 3 Installation 4) Robot overrun during impacts with mechanical stopper A urethane damper is installed to absorb the shock when an impact occurs with the mechanical stopper, so a certain amount of overrun occurs when the robot strikes the mechanical stopper. Use caution and take overrun into ac- count since the end effector may interfere with the robot body and peripheral equipment or the robot body may interfere with the peripheral equipment.
CHAPTER 4 Adjustment Overview YAMAHA robots have been completely adjusted at the factory or by the sales representative before shipment, including the origin position adjustment. If the operating conditions are changed and the robot must be adjusted, then follow the procedures described in this chapter.
The robot is shipped from the factory in condition "c" (below), so please perform absolute reset after installing the robot. For more details on abso- lute reset, refer to "Absolute Reset" in Chapter 4 of the "YAMAHA Robot Con- troller User's Manual".
CHAPTER 4 Adjustment Absolute reset method 3-1-1 Sensor method (X-axis, Y-axis, and R-axis) In the sensor method, the target axis is automatically operated for the absolute reset, and the absolute reset is performed at the position where the proximity sensor provided on the target axis detects the detection area (dog). The absolute reset in the sensor method can be executed with the teaching pendant (MPB), RS- 232C communication, and dedicated input.
CHAPTER 4 Adjustment Machine reference The YK-XG series position detectors are resolvers that have four positions where absolute reset can be performed per motor revolution. If the sensor method is used for the absolute reset, the origin position will be set at the positions where absolute reset can be performed soon after the origin sensor reacts to the dog (the origin signal is detected).
Never enter within the robot movement range during absolute reset. The operation procedure using the MPB is described next. (Press the ESC key on the MPB if you want to return to the preceding step.) See the "YAMAHA Robot Controller User's Manual" for information on operating the robot controller.
Page 86
CHAPTER 4 Adjustment 8) After the absolute reset is completed, check that the machine reference value displayed on the MPB is between 40 and 60 (recommended range). If the machine reference value is outside the recommended range, then the next absolute reset may not be properly performed.
Never enter within the robot movement range during absolute reset. The operation procedure using the MPB is described next. (Press the ESC key on the MPB if you want to return to the preceding step.) See the "YAMAHA Robot Controller User's Manual" for information on operat-ing the robot controller.
