What is the link number to attach a user model to the robot EOAT?
99
How many shape elements can be used to create a user model?
10
What is a geometric shape, like a sphere, that is attached to the root flange or arm?
Shape Model
If a Joint Speed Check is set up as safe inside between 200m/sec and 1000m/sec, how fast can the robot operate?
200m/sec - 1000m/sec
If a polygon is not configured correctly, what error will occur?

Cartesian Position Check
What is the default JPC/JSC scan time?
8msec
What definition below best describes a Stop Category 1 zone?
