To secure the

robot arm

1. Mount the robot on a sturdy, vibration-less, surface that can withstand at least

ten times the full torque of the base joint and at least five times the weight of the

robot arm.

If the robot is mounted on a linear axis, or a moving platform, then the

acceleration of the moving mounting base is very low. High acceleration might

cause the robot to make a safety stop.

2. Tighten the bolts to 20Nm torque. (Torque values have been updated SW5.14.

Earlier printed version will show different values)

3. Use the two Ø8 holes provided, with a pin, to accurately reposition robot arm.

3.4. Securing Tool

Description The tool or workpiece is mounted to the tool output flange (ISO 9409-1) at the tip of the

robot. All measurements are in millimeters.

1.2:

Dimensions and hole pattern of the tool. All measurements are in millimeters.

Tool flange The tool output flange (ISO 9409-1) is where the tool is mounted at the tip of the robot. It

is recommended to use a radially slotted hole for the positioning pin to avoid over-

constraining, while keeping precise position.

CAUTION

Very long M8 bolts can press against the bottom of the tool flange and

short circuit the robot.

•

Do not use bolts that extend beyond 10mm to mount the tool.
