• Selecting the Waveform
• When the data type is set to Binary or ASCII, the waveform that is displayed on
the screen is saved.
• When the data type is Float, the waveform of the input signal selected from the
following is saved.
• Only the input signals of the installed elements are applicable for the
selection.
• For models with the motor evaluation function (motor version), the input
signals of Speed and Torque are also selectable items.
