7.1 Installing End-Effectors
The user is responsible for providing and installing any end-effector or other end-of-arm
tooling. End-effectors can be attached to the user flange using four M6 screws. See Figure
9-3 on page 161 for a detailed dimension drawing of the user flange.
A 6 mm diameter x 12 mm dowel pin (not supplied) fits in the through hole in the user
flange and can be used as a keying or antirotation device in a user-designed end-effector.
If hazardous voltages are present at the end-effector, you must install a ground connection
from the base of the robot or the outer link to the end-effector. See “Robot-Mounted
Equipment Grounding” on page 63.
NOTE: A threaded hole is provided on the user flange (see Figure 9-3 on
page 161). The user may attach a ground wire through the quill
connecting the outer link and the user flange.
7.2 Removing and Installing the User Flange
The user flange can be removed and reinstalled if this is required for a specific reason. If
the flange is removed, it must be reinstalled in exactly the same position to avoid losing
the calibration for the system.
There is a setscrew on the flange that holds the rotational position of the flange on the
quill shaft. A ball bearing behind the setscrew contacts the shaft in one of the
vertical-spline grooves in the shaft. Follow the procedures below to remove and replace
the flange assembly.
Removing the Flange
1. Turn off High Power and system power to the robot.
2. Remove any attached end-effectors or other tooling from the flange.
3. Use a 2.5 mm Allen driver to loosen the setscrew (see Figure 7-1 on page 138).
Note the vertical-spline groove that is in line with the setscrew. You must replace
the flange in the same position.
4. Use a socket driver to loosen the two M4 socket-head screws.
5. Slide the flange down slowly until it is off the shaft. Be careful not to lose the ball
bearing (3.5 mm) that is inside the flange behind the setscrew.
