Position Dialog Box
A teachpoint is a point in space to which a device such as a robot or
bucket can move and is defined with respect to reference positions built
in to that device.
For example, when you define a VSpin bucket position, the bucket
position becomes a teachpoint where your robot can place a plate.
See "Creating and Managing Profiles" on page 37.
On the VSpin, the home position is the reference position used to orient
the rotor.
When you set the teachpoint for the VSpin, you are setting the angle
from the home position to the angle that the rotor turns to line a bucket
up with the door. The software designates this teachpoint as bucket
number one. This teachpoint must be set for operation.
The Teach Bucket Position dialog box is used to align the buckets to the
door by calculating a teachpoint value. In the following example, the
Current position of 7999 is where bucket number one lines up with the
door. Notice that this is the sum of the Home position value of 6689 and
the Teachpoint value of 1310.
When you tell the VSpin to go to bucket number one, it finds the Home
position and then moves an additional angle as defined by the
Teachpoint value, in this case 1310, to end up at position value 7999.
There are 8000 units in one revolution, so bucket two will be at a
position value that is 4000 units less than the bucket one position value.
In this case, that is 3999.
To see how to open and use the Teach Bucket Position dialog box, see
"Creating and Managing Profiles" on page 37.
