VS-050/060 Robot Calibration (Communication Interface Flange-A)

Modified on Tue, 22 Oct at 6:33 PM

Please read our Legal Disclaimer before executing any steps on this article.

Overview

CALSET must be performed when any of the motors is replaced, or the encoder backup battery goes dead so that the position-related data retained in the encoder is lost.

The CALSET data is different on each robot.

CALSET data should be managed by the customer. Back up the CALSET data periodically, referring to " Backing up Projects ".

Tools and Parts Needed

Philips-head screwdriver (depends on model)
Allen (hex) key (depends on model)
CALSET Jig
- 410192-0050 - 6th axis CALSET jig (Not included)

Note:
If you are not sure which part number, you need or the Robot Arm you own please stop and contact your DENSO Robotics sales representative.

Step by Step Guide (for all axis)

Previous Steps:

How to release axis brake (RC8)

1st Axis

Step 1

Positive-direction mechanical end (at the time of shipment)

2nd Axis

Step 1

Negative-direction mechanical end (at the time of shipment)

3rd Axis

Step 1

Positive-direction mechanical end (at the time of shipment)

4th Axis

The 4th axis physically rotates 360° or more but it is not a boundless rotation joint. It has no mechanical ends.

Follow the procedure below and set the 4th axis in a correct CALSET position.

Performing CALSET in a wrong position may break internal wiring.

Step 1 Release the brake of the 4th axis. Refer to "Releasing Brakes on Individual Axes".
Step 2 Rotate the 4th axis slowly by hand in the positive direction (counterclockwise, seen from the top end of the arm) until it gets blocked (around 360°). NOTE Slowly rotate the axis. If it gets blocked, do not push it hard further. If the axis does not get blocked even if you rotate it two turns or more, internal over-rotation prevention tape may be damaged. Repair and replacement are required. Please contact Denso services.
Step 3 Rotate (Return) one turn in the negative direction (clockwise, seen from the top end of the arm) by hand until it comes to the following position (around 0°).
Step 4 Rotate the 4th axis from the position in STEP 3 until it comes to the following position (around plus 30°). Set the 4th-axis CALSET bolt in that position shown in the figure. The 4th-axis CALSET bolt is stored in the encoder backup battery box. Refer to "Encoder Backup Battery Box".
Step 5 Rotate the 4th axis in the negative direction by hand and gently press it against the 4th-axis CALSET bolt for performing CALSET.

5th Axis

Step 1

Determine the CALSET position of the 5th axis of the VS-050/060 using the 4th-axis CALSET bolt.

Set the 4th-axis CALSET bolt in the position shown on the right, and then gently press the 5th axis against the negative-direction end by hand. (The 4th-axis CALSET bolt is stored in the encoder backup battery box. Refer to "Encoder Backup Battery Box".)

6th-Axis CALSET Position (Communication Interface Flange-A)

Calset Jig Assembly

Step 1

Remove the CALSET pin for the communication interface flange-A.

Step 2

Mount the CALSET pin to the place the drawing on the right indicates.

Tightening Torque: 2.0 +/- 0.4 Nm

Step 3

Remove the CALSET bolt for the communication interface flange-A

Calset Jig Installation

Step 1 Turn the 6th axis until being able to see the orange film from a half of the window next to the flange. In case of not being able to see the orange film from the window next to the flange at all, turn the 6th axis to the negative direction (clockwise from the front of the flange). In case of being able to see the orange film from the entire window, turn the 6th axis to the positive direction (anti-clockwise).
Step 2 Set the 6 axis to the place drawing on the right indicates. (Near the 0 degree)
Step 3 Mount the CALSET bolt for the communication interface flange-A. Tightening Torque; 0.8+/-0.1Nm
Step 4 Mount the CALSET jig. Tightening Torque：8.8 +/- 1.7 Nm
