D/A Output (D/A Output, option)

You can generate numeric data as ±5 V FS DC voltage signals from the rear panel D/A output terminal. You can 
set up to 20 items (channels).

Output Items (Item)

The measurement functions that you select under Function and Element/Σ appear here.

Function (Function)

•  You can select any of the measurement functions listed under “Items That This Instrument Can Measure.”

Click here.

•  To output integrated values through D/A conversion, set the rated time for integrated D/A output.

Click here.

•  You can also choose not to output a measurement function (None). The output for channels that have been 

set to none is 0 V, because they have no corresponding numeric data.

•  When the 

D/A output range mode

 is set to Fixed, the D/A output of channels whose measurement function 

has been set to Z, Rs, Xs, Rp, Xp, Utif, Itif, or F1 to F20 is Fixed at 0 V. When the range mode is manual, the 
channels produce voltages.

Element (Element/Σ)

•  When the function (Function) is set to something other than Speed, Torque, Pm, Slip, or SyncSp

•  Depending on the function, select the element/wiring unit from the following options, or you may not need 

to select it. The available options vary depending on the installed elements.

  Element1, Element2, Element3, Element4, Element5, Element6, Element7, ΣA, ΣB, ΣC

•  If an element in the selected wiring unit does not exist, because there is no data, the output is 0 V. For 

example, if elements are assigned to ΣA but not to ΣB, the output for the measurement function for ΣB is 0 V.

•  If you set the function (Function) to Speed, Torque, Pm, Slip, or SyncSp, you can select the motor number 

(Motor 1, Motor 2, Motor 3, or Motor 4).

Harmonic Order (Order (k))

When you select a function that has harmonic data, you can set the displayed harmonic order within the 
following range.
Total (Total value) or 0 (DC) to 500

The harmonic orders that can be specified vary depending on the measurement function. For details, see 
“Harmonic Measurement Function Orders.”

Click here.

The outputs of orders that exceed the maximum measurable order are 0 V. For information about the maximum 
measurable harmonic order, see “Maximum Harmonic Order to Be Measured (Max Order).”

Click here.

D/A Output Range Mode (Range Mode)

You can select the D/A output range mode from the following options.

Fixed (Fixed)

When a measurement function’s rated value is received, +5 V is output. For details, see “Relationship between 
Output Items and the D/A Output Voltage.”
