3.5.2 System Layout
When designing the layout for a robot system, be sure to fully take into account the possibility of interference between robots
and peripheral equipment. Particular attention must be paid to emergency stops because a robot will stop after following a path
that is different from its normal movement path. The layout design should provide adequate margins for safety. Ensure that the
layout provides ample space for maintenance and inspection work.
When using the high-speed manual mode, maintain a clearance of 500 mm between the robot and surrounding buildings,
structures, perimeter protection, and other equipment.
When designing a robot system to restrict the area of motion of the robots, do so by following the methods described in the
Manipulator manual. Limiting is done either by Soft Axis Limiting or by mechanical stops. For Soft Axis Limiting, refer to the
following manual.
"Robot Controller Safety Function Manual"
For limiting by mechanical stops, refer to the following manual.
"Manipulator Manual"
Ensure to install the emergency stop switch at a location near the operation unit for the robot system where the operator can
easily access the switch to immediately press it in an emergency.
Do not install the Controller at a location where water or other liquids could enter the Controller. Never use water or other
liquids to clean the Controller.
To ensure that lockouts are implemented safely during servicing and maintenance, disconnectors should be located outside the
safeguard wherever possible.
3.5.3 Disabling Power to the System Using Lockout/Tagout
Disconnect the Controller's power supply using the lockout/tagout procedure to ensure a third party does not accidentally turn
on the robot while a worker is inside the safeguard for maintenance or repair. For more information on lockout, refer to the
following section.
Part Names and Their Functions
3.5.4 Hand Design
Perform the wiring and piping work so that the robot hand will not release the workpiece (object being grasped) even when the
robot system power is shut off.
Design the robot hand such that its weight and moment of inertia do not exceed the allowable limits. Use of a robot hand that
exceeds the allowable limits can subject the robot to excessive loads. This will not only shorten the service life of the robot but
can lead to unexpectedly dangerous situations due to the additional external forces applied to the hand and the workpiece.
Be sure to select the size of the hand with care because the robot body and robot hand could interfere with each other.
3.5.5 Peripheral Equipment Design
When designing equipment that removes and supplies parts and materials to the robot system, ensure that the design enables
adequate safety for the operator. If it is necessary to remove or supply materials without stopping the robot, install a shuttle
device, use SLP, or take other measures to ensure that the operator does not need to enter a potentially hazardous zone.
Ensure that an interruption to the power supply (power shutoff) of peripheral equipment will not lead to a hazardous situation.
In addition to taking measures to prevent release of held workpieces as mentioned in "Hand Design," measures must also be
taken to ensure peripheral equipment other than the robots can stop safely. Verify equipment safety to ensure that no hazardous
situations will occur if the power is cut off.
