• The threshold value at which on/off switching will occur will be the middle value between
the maximum and minimum input voltage values (the value equal to the sum of the maximum
and minimum values divided by two). To prevent malfunctions, you should allow plenty of
room for detection (see “GPI Calibration” dialog box).
• If the voltage has dropped because of cable length or noise, use the “GPI Calibration” dialog
box to adjust the maximum and minimum input voltage values. Since voltage may become
unstable, configure and set up your external circuit to ensure that there is ample distance
between the maximum and minimum values.
【 Analog】
You can select this option if you assigned a continuously-changing parameter to the [Parameter Value Edit]
category.
• The level will be at the maximum value when the input voltage to the GPI IN is at maximum (5V), and at
the minimum value when the input voltage is at minimum (0V).
【 Analog Inv.】
You can select this option if you assigned a continuously-changing parameter to the [Parameter Value Edit]
category.
• The level will be at the minimum value when the input voltage to the GPI IN is at maximum (5V), and at the
maximum value when the input voltage is at minimum (0V).
【 High Active】
You can select this option if one of the following functions was assigned.
• Device Mute
• GPI Lock
