6.6 Write Data Formats (continued)
6.6.2 Preset Position Instruction
This command alters the internal position offset. If the Total Measurement Range equals zero:

The offset is stored in RAM.

This offset will be lost once power is cycled to the NR60E2.

If you wish to save the internal position offset, you must issue a Save To Flash Instruc-
tion as described below.
If the Total Measurement Range does not equal zero, the position offset is automatically stored
in nonvolatile memory. A Save To Flash Instruction is not required.
Four bytes of data must be written to the NR60E2 as part of this instruction. Table T6.6 lists the format of the
data words. The location of these words must be entered into the message instruction using the
Source Ele-
ment field.

6.6.3 Save To Flash Instruction
This instruction saves parameter values and the internal position offset to nonvolatile memory. Additional
data is not sent with this instruction. Set data length fields to 0 and leave the source field blank.
6.6.4 Restore From Flash Instruction
This instruction restores parameter values to the last values saved in nonvolatile memory. Additional data is
not sent with this instruction. Set data length fields to 0 and leave the source field blank.
6.6.5 Restore Factory Defaults Instruction
This instruction restores parameter values to their factory defaults. The Attribute field is not used and should
be set to zero. Additional data is not sent with this instruction. Set data length fields to zero and leave the
source field blank.
This instruction does not reset the IP Address, Network Mask, or Default Gateway parameters.
See Task 3,
Set the IP Address and Protocol , which starts on page 33, for information on
changing these settings.
This command stores the factory default values in RAM memory. You must issue a separate
Save To Flash instruction to store these values in non-volatile memory.
6.6.6 Reset Device Instruction
This instruction forces the NR60E2 to perform a hardware reset. Network communications will be lost
momentarily and all parameter values will be restored from nonvolatile memory. The Attribute field is not
used and should be set to zero. Additional data is not sent with this instruction. Set data length fields to zero
and leave the source field blank.

Preset Value.
The value that you want the position to become when you issue this
command. The Preset Value can be any number between 0 and the configured
full scale count of the encoder. The values on the right show the register val-
ues in hexadecimal if the Preset Value is 704,303 (16# 000A BF2F)
The type of NR60E2 that you are using, as well as the Scaling Function Control and
Total Measurement Range parameters affect the range of the Preset Value.
See
Preset Value on page 19 for the acceptable ranges of parameter values for
the different NR60E2 models.
