Enable:
A physical encoder is connected to the Encoder input and is enabled
Encoder Step (mm/pulse)
Click to activate the Encoder Step input form. Enter the Encoder Wheel Circumference in
the field provided and select the in or mm option. Enter the Pulses / Revolution in the field
provided (See the table below for values). Click
Submit to save the values, or click Cancel to

Encoder Step Settings Table
Encoder Resolution
Displays the encoder/tachometer resolution in pulses per inch (PPI) based on the Encoder Step
calculation. This field cannot be edited.
Conveyor Speed (max/constant) (m/sec)
When the Physical Encoder is enabled the formula for the Max Conveyor Speed is calculated.
The formula is not used when the Physical Encoder is disabled.
When disabled there is no physical tach connected to the camera. The Max Conveyor Speed
option uses an internal clock that sets the tach to match the conveyor speed.
Formula: Max conveyor speed x 1.05
See “AV500 System Elements Positioning” on page 102
