C12 Maintenance 16. Calibration
642 C Series Maintenance Manual Rev.2
After resetting the error, the motor encoder of the joint whose parts have been
replaced will be initialized.
Set the jog mode to “Joint” in [Jog & Teach] and operate the Manipulator in jog
motion to match the home position marks (0 pulse position) of the joint
accurately.
When the joint cannot move to the home position, operate the Manipulator to
match the tram mark placed in
C Series Manual C12 Manipulator 3.7 Checking
the Basic Orientation as accurate as possible.
Initialize the encoder when the joint matches the home position or the tram mark.
For the encoder initialization, refer to the procedure indicated above.
When the origin of the Joint #5 is calibrated, the Joint #6 will be out of position.
(Due to the structure of the Manipulator, any offset in the position of the Joint
#5 affects the Joint #6.)
Calibrate the origin of the Joint #6 together when calibrating the Joint #5.
