Programmable Parameters (continued)
Scaling Function Control
This parameter determines if the position value reported in the network data is scaled to engineering units or
if it is reported at its full 16 bit resolution. Scaling is accomplished with the
Counts per Turn
and
Total Mea-
surement Range
parameters. (see below)
A value of “0” disables scaling. The position and velocity data is reported at 16 bit resolution.
A value of “1” enables scaling. The position and velocity data is reported in the engineering units set by
the
Counts per Turn
and
Total Measurement Range
parameters.
Velocity data is scaled by the
Measuring Units per Revolution
parameter if the parameter is
enabled. The exception is when velocity data is reported in revolutions per minute (RPM).
This parameter is forced into its disabled state when the Class 4 Functionality parameter is set
to its disabled state. Therefore, if the Class 4 Functionality parameter is set to its disabled state,
the Scaling Function Control, MUR, and TMR parameters are ignored and the NR60E2
reports position at its maximum resolution and number of turns.
Counts per Turn
This parameter is called
Measuring Units Per Span
in EtherNet/IP systems. This parameter is called
Code
Sequence
in PROFINET systems. This parameter is used to scale the position and/or velocity data. This
parameter is disabled when the
Scaling Function Control
parameter is set to its disabled state.
Values can range from 2 to 65,536 counts per turn for single turn NR60E2 units.
Values can range from 1 to 65,536 counts per turn for multi-turn NR60E2 units.
Changing the Counts per Turn parameter clears the internal position offset. The current posi-
tion reference will be lost. Changes to this parameter should be made before the position is
preset.
The number of turns encoded by the NR60E2 is not controlled with this parameter. The
Total Measurement
Range
parameter is used to control when the position data rolls over to zero, which controls the number of
turns encoded by the NR60E2.
Total Measurement Range
The
Total Measurement Range
parameter sets the total number of counts before the position value returns to
zero. It places an upper limit on the position value and the
Preset Value
parameter. This parameter is disabled
when the
Scaling Function Control
parameter is set to its disabled state.
The
Total Measurement Range
parameter has the following ranges:
Single Turn NR60E2
: Range of 2 to 65,536
28 bit Multi-turn NR60E2:
Range of 2 to 268,435,456
30 bit Multi-turn NR60E2:
Range of 2 to 1,073,741,824
Changing the
Total Measurement Range
parameter clears the internal position offset. The cur-
rent position reference will be lost. Changes to this parameter should be made before the posi-
tion is preset.
Note that the value of the
Counts Per Turn
parameter does not limit the range of values that can be pro-
grammed into the
Total Measurement Range
parameter. There is no fixed relationship between the
Total
Measurement Range
and
Counts per Turn
parameters, which leads to interesting applications that use the two
parameters.
