Saving and Loading Data
• Selecting the Numeric Data
Select the numeric data items that are to be saved.
• Installed elements and wiring units are applicable for the selection.
• Measurement functions can be selected as follows:
For measurement modes other than cycle-by-cycle measurement
• Measurement functions of normal measurement (see section 2.2)
• Measurement functions of the motor evaluation function (motor version)*
• Measurement functions of harmonic measurement (option)*
For cycle-by-cycle measurement mode
• Measurement functions of cycle-by-cycle measurement*
* See the Expansion Function User’s Manual IM760301-51E.
• The following data is saved in the places where numeric data does not exist
when saving the numeric data.
• For ASCII files: Characters NAN, +INF, -INF, ERROR, or blank
*1
.
*1 Measurement functions that are displayed as blank such as the 0th (dc) and 1st
order values of
φ
U and
φ
I.
• For Float files: 0x7FC00000, 0x7F800000, 0xFF800000, or 0xFFFFFFFE.
• When saving the cycle-by-cycle measurement data, information indicating
whether peak over-range occurred during the measurement is recorded to the
right of the voltage (U), current (I), speed, and torque data values using a
number between 0 and 7. There are two methods for detecting peak over-range:
detection by data and detection by hardware. The peak over-range information
that is recorded is a combination of these detection results. See below.
Peak over-range detection by hardware
Did not occur
Occurred
Peak over-range data did not occur
0
4
Positive peak over-range data occurred
1
5
Negative peak over-range data occurred
2
6
Positive and negative peak over-range data occurred

7
Note
If any hardware peak over-range is detected during the measurement of all cycles, a number
between 4 to 7 is recorded for the data of all cycles of that input signal.
• Saving the Waveform Sampling Data
Select Acquisition from the File Item menu to save waveform sampling data.*
