Available Data
All NR60E2 encoders offer position and velocity data that can be scaled with the programmable parameters
as described in the following section. The position data can also be preset which allows you to align the posi-
tion data with your machine position without having to physically rotate the shaft.
Programmable Parameters
The following parameters are available on all NR60E2 encoders. Units configured for the PROFINET proto-
col, use encoder objects that are defined by these protocols. Therefore, these units have additional parameters
that are protocol specific. These parameters are explained in the PROFINET protocol section,
PROFINET
Parameters starting on page 75.
Count Direction
This parameter is called Code Sequence in PROFINET systems. This parameter allows you to set the direc-
tion of shaft rotation needed to produce increasing counts. The default is CW when looking at the shaft.
Effects of Reversing Count Direction
Changing the Count Direction parameter changes the way the position value is calculated. When you reverse
the count direction, the position changes from your current position value to (Maximum number of counts –
current position value). For example, assume a 30 bit NR60E2 with its default of 65,536 counts per turn. If
the current position value is 100,000 and you change the Direction Counting Toggle parameter, the current
position will change to (2
30
– 100,000 = 1,073,741,824 – 100,000) = 1,073,641,824.
Most applications do not require you to change the count direction after the machine is setup, so the count
direction is typically set before the position value is preset.
Changing the count direction on your machine while maintaining the current position value is a three step
process. First, read and store the current position value from the NR60E2. Second, change the
Count Direc-
tion value. Third, write the stored position value back to the NR60E2 as a preset value.
