*1 For the position command, current position, and droop pulse, if either the parameter for the upper or lower digits is selected in the Wave section,
"Unselected" is shown for the channel and the waveform is not displayed. Even when both upper and lower digit parameters are selected,
"Unselected" is shown for the channel for the upper digit parameter. The upper digit value is connected to the lower digit value, and the monitor
item name is shown for the channel for the lower digit parameter. The waveform is displayed for the channel for the lower digit parameter.
*2 When the winding length (upper) and the winding length (lower) are monitored, if only the winding length (upper) is selected in the Wave section,
"Unselected" is shown for the channel and the waveform is not displayed.
NOTE
• Virtual network terminals are displayed for the digital data when the high speed mode is selected.
 Setting range and setting unit of sampling interval and sampling time
• The setting range of the sampling interval and sampling time are different for high speed sampling and monitor sampling.
• High speed sampling (only for direct USB/Ethernet connections between inverters and the personal computer)
The sampling interval can be about 0.125 [ms] (mask count 0) to about 20 [ms] (mask count 30). The sampling time can
be up to "(mask count + 1) × 4000". The sampling interval varies depending on the control mode.
• Monitor sampling
The sampling interval and the sampling time vary depending on communication settings. The minimum sampling interval
is calculated by multiplying the number of sampling items by the lower limit value. The lower limit of the sampling interval
is as shown in the following table.
Communication port
Serial port
USB
Ethernet
For the sampling interval and sampling time maximum values, minimum values, and setting units under actual
measurement conditions, refer to the following table.
Sampling interval [ms]
Sampling time [ms]
*1 If an alarm trigger is set, the alarm trigger is also counted as a sampling item.
*2 Even if a sampling time shorter than 3000 [ms] is set, the minimum sampling time of 3000 [ms] applies.
Example: Connected to the serial port with a communication speed of 19200 bps, when monitoring three items of output
frequency, output current, and output voltage as data items to be displayed in a graph.
Initialize sampling settings.
Set the measurement mode for sampling.
Mask count Set the interval for data sampling measurement.
Measurement Displays the maximum time for data sampling measurement.
time (ms)
Set the condition to start sampling measurement.
Selects the station to be set for sampling.
Selects the items to be sampled. For analog data, 4 CHs (8 CHs of trace data) can be selected, and
for digital data, 4 CHs (8 CHs of trace data) can be selected.
Shows a description of the currently selected item.
Closes the currently-selected tab ([Setting], [Indication], or [Cursor]) of the property window. To open
the closed tab again, from [Graph (Z)] of the menu bar, choose [Property window] and click the tab to
open.
