FUNCTION
4.9.4 Sampling setting
Click to display Sampling setting section. Setting sampling mode, Single/Continuous setting, and sampling
time are available.
No. Name Function and description
A
Single/Continuous
Select between Single sampling or Continuous sampling.
• Single:
Sampling from start to end is performed only once.
• Continuous:
Sampling from start to end is performed continuously. When sampling ends, the data is
added to History, and starts the next sampling. (Refer to page 147)
B
Mode
Select between High Speed sampling or Monitor sampling.
High speed sampling is available when an FR-A700 or FR-E700 series model is connected
via USB (not available when the inverter is connected via GOT. ) Since some monitor items
are different between the sampling mode, the setting of uncommon sampling item is cleared
when changing the sampling mode
C
Interval [ms]
Set interval (cycle) of data sampling.
Sampling interval is fixed depending on a number of sampling items and communication
setting. (Refer to page 142)
Mask Count
Set interval (cycle) of data sampling.
For High Speed sampling, set Mask count (available from 1 to 40) for the sampling interval.
Refer to the following formula for sampling interval.
Sampling interval is approximately equal to (Mask Count + 1) 0.5ms
Example: when the Mask Count is 1
Sampling interval is approximately equal to (1 + 1) 0.5ms = About 1ms
D
Time [ms]
Set maximum sampling time. When elapsed time exceeds the sampling time, sampling
stops. Maximum sampling time can be set as follows. (Refer to page 142)
High Speed sampling: Maximum sampling interval 8000
Monitor sampling: Maximum sampling interval 10000
Example: when the Mask Count is 1 for High Speed sampling
Maximum sampling time = 8000ms
