Configuring the 842 E encoder using RSLogix 5000 Chapter 6
Configuration tab
The Configuration tab is used to configure the encoder scaling, direction, and
set velocity units. Click the Enable Scaling checkbox to change the encoder
resolution. Use the Direction drop down box to set the direction of the encoder
(check the definition in the old user manual). Use the velocity units to set the
velocity units of the encoder.
Scaling makes it possible to scale the steps per revolution and the total resolution
(see “Linear scaling example” on page 53 in Appendix B).
If the Enable Scaling box is checked, the values can be entered for the steps per
revolution and the total resolution applied.
Direction: The direction of rotation (increasing position value), viewed on the
shaft, can be set to clockwise or counterclockwise.
• Clockwise = increasing position value on clockwise revolution of the shaft
• Counterclockwise = increasing position value on counterclockwise
revolution of the shaft.
Velocity units: Use this parameter to define the units in which the velocity is
transmitted. The options are the following:
• Counts/sec
• Revolutions/sec
• Revolutions/min
