3 Special Training for Industrial Robot Operation
Companies or factories using industrial robots must make sure that every person, who handles the robot such as for teaching, programming, movement check, in­spection, adjustment and repair, has received appropriate training and also has the skills needed to perform the job correctly and safely. Since the YAMAHA YP-X Series pick-and-place robots fall under the industrial robot category, the user must observe local regulations and safety standards for industrial robots, and provide special training for every person involved in robot­related tasks (teaching, programming, movement check, inspection, adjustment, repair, etc.).
CHAPTER 1 Using the Robot Safely
1-9
4 Robot Safety Functions
(1) Overload detection
This function detects an overload applied to the motor and shuts off the servo power.
(2) Overheat detection
This detects an abnormal temperature rise in the controllers driver and shuts off the servo power. If an overload or overheat error occurs, take the following measures.
1. Insert a timer in the program.
2. Reduce the acceleration coefficient.
(3) Soft limits
Soft limits can be set on each axis to limit the working envelope in manual operation after return-to-origin and during automatic operation. The working envelope is the area limited by soft limits.
(4) Mechanical stoppers
If the servo power is suddenly shut off during high-speed operation by emer­gency stop or safety functions, these mechanical stoppers prevent the axis from exceeding the movement range. The R-axis has no mechanical stopper. The movement range is the area limited by mechanical stoppers.
WARNING
Axis movement does not stop immediately after the servo power supply is shut off by emergency stop or other safety functions.
(5) Z-axis (vertical axis) brake (Option)
An electromagnetic brake can be installed to the Z-axis as an option, to prevent the Z-axis from sliding down when the servo power is turned off. This brake is working when the controller is off or the Z-axis servo power is off even when the controller is on. The Z-axis brake can be released by means of the pro­gramming unit or by a command in the program when the controller is on.
WARNING
The Z-axis will slide down when the Z-axis brake is released, caus­ing a hazardous situation.
Press emergency stop button and prop the Z-axis with a support stand before releasing the brake.
Use caution not to let your body get caught between the Z-axis and installation base when releasing the brake to perform direct teach.
WARNING
Axis movement does not stop immediately after the servo power supply is shut off by emergency stop or other safety functions.
CHAPTER 1 Using the Robot Safely
1-10
5 Safety Measures for the System
Since the robot is commonly used in conjunction with an automated system, a dangerous situation is more likely to occur from the automated system than from the robot itself. Accordingly, appropriate safety measures must be taken on the part of the system manufacturer according to the individual system. The system manufacturer should provide a proper instruction manual for safe, correct opera­tion and servicing of the system.
CHAPTER 1 Using the Robot Safely
1-11
6 Trial Operation
After installation, adjustment, inspection, maintenance or repair of the robot has been done, perform a trial operation using the following procedures.

CHAPTER 1 Using the Robot Safely
1-16
13 Precautions
1) Accuracy may deteriorate due to external causes such as temperature and humidity and may result in equipment breakdowns. Use of the robot in air­conditioned facilities is recommended. Do not use in environments exposed to items such as oil, water, corrosive gases and metal powder etc.
2) When using the robot after an extended period of non-use, warmup the robot for about a 10 minute period with no workpiece installed. This will improved the sliding operation of the mechanism.
3) If the work (including the gripper or tool) is heavier than the maximum pay­load listed in the catalog or the robots own basic settings are changed, this may cause the robot itself to breakdown. Do not use the robot under such conditions.
4) Because of the one-sided support structure, the YP-X series manipulator arm droops downward slightly when it moves to the X-axis stroke end (forward end). For example, the manipulator arm will droop a maximum of 1.5 millimeters with a payload of 3kg, so take this into consideration during the application design stage.
5) If the robot movement duty is too high, errors such as "Overload" and "Over­heat" may occur. In this case, increase the time that the robot axis is stopped by inserting a timer in the program, etc.
6) The YAMAHA pick and place robot uses the stroke-end origin detection method. In this method, a large electrical current flows through the motor, so avoid performing absolute reset frequently to prolong the controller and mo­tor service life.
7) The axes on the YP-X series are belt-driven (see specifications). Using the motor to apply thrust (press-fit, etc.) may sometimes cause the teeth on the belt to jump free. So use caution not to apply a large force greater than the maximum payload listed in the specs for the Z-axis.
8) On the YP-X series, a slight residual vibration may sometimes occur during positioning of each axis due to the one-sided support structure and the belt drive. So install a timer if precise positioning is required.
