10 Waveform Display
Waveform Display (WAVE)
You can press WAVE to make the waveform displays of the following types of input signals.
• Input element voltage and current
• Motor evaluation function (option) speed and torque
• Auxiliary inputs (option) Aux1 and Aux2
Each time you press WAVE, the number of split screens switches in order between none, 2, 3, 4, and 6.
Waveform Display Example
Time at the right edge
of the screen
(amount of time contained
in the screen)
Time at the left edge
of the screen
(fixed at 0 seconds)
• The number of data points between the left and right edges
of the display.
• “P-P” indicates that the displayed waveform has been P-P
compressed.

Measurement Mode during Waveform Display
When waveforms are displayed, the measurement mode indicated in the upper left of the screen is Normal Mode
(Trg). After a
occurs, measurement takes place at the data update interval.
• If you do not set the trigger level properly, the waveform display start point (the signal level on the left edge
of the screen) may be unstable, or waveforms may not appear.
• Even when waveforms are displayed, in the following situations, the measurement mode indication at the
upper left of the screen is Normal Mode.
• During integration
• When the trigger mode is OFF
In Normal Mode, measurements are taken and the sampled data is updated automatically at the data
update interval. In this mode, there are limitations on the waveform display feature.
