6.6 Write Data Formats
6.6.1 Configure NR60E2 Data Format
This command writes parameter values to RAM. These parameter values will be lost once
power is cycled to the NR60E2. If you wish to use these parameters after cycling power, you
must write them to the NR60E2 again, or you must issue a
Save To Flash Instruction as
described on page 65.
Twelve bytes of data must be written to the NR60E2 as part of this instruction. Table T6.5 lists the format of
the data words. The location of these words must be entered into the message instruction using the
Source
Element field. All data must be present and valid when programming the NR60E2.

Direction Counting
Toggle
“0” = Clockwise increasing counts looking at shaft.
“1” = Counter-Clockwise increasing counts looking at shaft.
1
Scaling Function
Control
“0” = Disable Scaling Function. The full resolution of 65,536 counts
per turn is used for the Measuring Units per Span.
“1” = Enable Scaling Function. The number of counts per turn is set
by the Measuring Units of Span parameter below.

2
Counts per Turn
Sets the number of counts generated over a single turn if the
Scaling Function Control parameter equals “1”. Always sets the
number of pulses per turn reported in velocity data. This value
ranges from 1 to 65,536 and must be set even when the Scaling
Function Control value equals zero. A value of 39,370
(16#99CA) is shown to the right. CA

Sets the number of counts before returning to zero. This value is
used regardless of the state of the Scaling Function Control
parameter. Parameter ranges:

6 Velocity Format
Format of the velocity data. Byte 11 must always equal “1F”.
Byte 10 = “04” for pulses/second, “05” for pulses/millisecond,
“07” for pulses/minute or “0F” for revolutions/minute. A value
of “1F04” to the right would set the unit of measure to pulses/
second.
