The detection object for the standard configuration of the LV-1700 series is vibration velocity (m/s). Therefore, in the configuration, only AC component of the analog voltage signal is outputted by the high-pass filter. When the velocity is measured at the ramp up and down control stage, the output decreases and falls to 0 when the stage velocity is fixed, so the DC detection cannot be operated in this configuration. (Following figure "Standard model") To enable the measurement of the correct velocity waveform when the stage velocity is fixed, the modification is required. (Following figure "Modification model of [DC-enabled]")
