Gocator 2300 & 2880 Series
Gocator Web Interface • System Management and Maintenance • 64
Encoder resolution is expressed in millimeters per tick, where one tick corresponds to one of the four
encoder quadrature signals (A+/ A- /B+ / B-).
Encoders are normally specified in pulses per revolution, where each pulse is made up of the
four quadrature signals (A+/ A- /B+ / B-). Because Gocator reads each of the four quadrature
signals, you should choose an encoder accordingly, given the resolution required for your
application.
To configure encoder resolution:
1. Go to the Manage page and click on the Motion and Alignment category.
2. In the Encoder section, enter a value in the Resolution field.
Encoder Value and Frequency
The encoder value and frequency are used to confirm the encoder is correctly wired to the Gocator and
to manually calibrate encoder resolution (that is, by moving the conveyor system a known distance and
making a note of the encoder value at the start and end of movement).
Travel Speed
The Travel Speed setting is used to correctly scale scans in the direction of travel in systems that lack an
encoder but have a conveyor system that is controlled to move at constant speed. Establishing the
correct travel speed is required for correct scaling of the scan in the direction of travel.
Travel speed is expressed in millimeters per second.
To manually configure travel speed:
1. Go to the Manage page and click on the Motion and Alignment category.
2. In the Speed section, enter a value in the Travel Speed field.
Travel speed can also be set automatically by performing an alignment with Type set to Moving (see
Aligning Sensors on page 94).
Jobs
The Jobs category on the Manage page lets you manage the jobs stored on a sensor.
