14.1 About Calibration

After parts have been replaced (motors, reduction gear units, timing belts, etc.), the
Manipulator cannot execute the positioning properly because a mismatch exists between the
origin stored in each motor and its corresponding origin stored in the Controller.
After replacing the parts, it is necessary to match these origins.
The process of aligning the two origins is called "Calibration". Note that calibration is not
the same as teaching*.
*: "Teaching" means to teach the Controller coordinate points (including poses) anywhere
in the operating area of the Manipulator.
■ To ensure safety, a safeguard must be installed for the robot system.
For details on the safeguard, refer to EPSON RC+ User's Guide: 2.4 Installation
and Design Precautions.
■ Before operating the robot system, make sure that no one is inside the
safeguarded area. The robot system can be operated in the mode for teaching
even when someone is inside the safeguarded area.
The motion of the Manipulator is always in restricted (low speeds and low power)
WARNING
status to secure the safety of an operator. However, operating the robot system
while someone is inside the safeguarded area is extremely hazardous and may
result in serious safety problems in case that the Manipulator moves
unexpectedly.
