Calibration and battery
6.1.
Introduction
Calibration associates the angle of each robot axis with the pulse count value supplied from the absolute
Pulse coder connected to the corresponding axis motor. To be specific, calibration is an operation for
obtaining the pulse count value, corresponding to the home position.
Factory calibration data is supplied in a separate document when purchasing the robot. These data are
unique as per robot serial number.
Calibration is factory-performed. It is unnecessary to perform calibration in daily operation. However,
calibration becomes necessary after:
Motor replacement
Pulse coder replacement
Reducer replacement
Cable replacement
Batteries for pulse count backup in the mechanical unit have gone dead
CAUTION
The data, including home position and the pulse encoder, are stored in
memory powered by the batteries. The data may get lost when the batteries
run out. It is necessary to replace the batteries of control device and robot
periodically.
