13.4 Calibration Procedure without using Calibration Wizard
This section indicates the calibration without using the calibration wizard of EPSON RC+.
For details of calibration using the calibration wizard, refer to Maintenance: 13.2
Calibration Procedure.
When coordinates for the Manipulator working point require calculation, it is important
for Joint #2 to be calibrated accurately. Execute the procedure in “Calibration Using
Right / Left Arm Orientations” to accurately calibrate Joint #2. For details, refer to
Maintenance: 13.3 Accurate Calibration of Joint #2.
You cannot calibrate Joint #4 alone because of the structure of the Manipulator. When
calibrating Joint #4, you must calibrate Joint #3 and #4 at the same time.
The reference point (a point to identify the position of the manipulator) needs to be
specified for calibration.
Follow steps
1 to 6 described below in order to calibrate the origin.
1.
Basic Pose Confirmation
(1
)-1 After the part replacement, execute the calibration using the
point data
currently registered.
Confirm the point data number (P*) to reconstruct the correct manipulator
position.
* Point data before the parts replacement
(motor, reduction gear, belt, etc.) is
necessary for the calibration.
2.
Part Replacement
(2)
-1 Replace parts as dictated by this manual.
* Be careful not to injure yourself or damage parts during part replacement.
3.
Encoder Initialization
(3)
-1 Turn ON the Controller when all joints are in the motion range.
(3)
-2 Manually move the joint that needs origin alignment to its approximate 0
pulse position.
0 pulse position of Joint #1:
position aligned with X-axis in
Robot coordinate system
