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.

Vel o ci t y un i t s : Use this parameter to define the units in which the velocity is

transmitted. The options are the following:

• Counts/sec

• Revolutions/sec

• Revolutions/min
