5 DriveProgramming User Variables
Analog Input Terminal Variables XA(0) to XA(2)
You can use the inverter's frequency reference input (analog voltage input) Ai1 terminal and the fre-
quency reference input (analog current input) Ai2 terminal as the analog input terminal variables XA(0)
and XA(1) of the DriveProgramming function.
It is also possible to use the frequency reference auxiliary input (analog voltage input) Ai3 terminal as
the analog input terminal variable XA(2) of the DriveProgramming function.
You can continuously monitor the status of the analog inputs regardless of the parameter settings.
Function
variable
XA(0) 0 to 10 V /0 to 20 mA
(Ai1 terminals)
XA(1) 10 V or less /0 to 20 mA
(Ai2 terminals)
XA(2) −10 to 10 V
(Ai3 terminals)
• The analog input terminal variables XA(0) and XA(1) are unsigned 1-word variables, and XA(2) is a
signed 1-word variable. This variable is read-only.
• The variables are displayed in increments of 0.01% as a percentage of the maximum analog input
10 V or 20 mA.
• You can allocate inverter functions to the analog input terminals with the inverter parameters as
shown below. Select a function in each parameter.
If you use the analog input terminals only for the DriveProgramming, do not select the analog input
terminal in the following parameters: (AA101, AH-51, AH-70, AA101, AA102, bA110, Ad-01)
• To adjust the analog inputs, use the following inverter parameters: (Ai1: Cb-03 to Cb-07, Ai2: Cb-13
to A105, Cb-13 to Cb-17 and Ai3: Cb-23 to Cb-26).
Precautions for Correct Use
When the DriveProgramming program is stopped, the status of the analog input terminal vari-
ables is not retained but updated according to the status of actual input terminals.
Analog Output Terminal Variables YA(0) to YA(2)
You can use the inverter's digital output (PWM output) FM terminal and the analog output (voltage out-
put) Ao1 terminal as the analog output terminal variables YA(0) and YA(1) of the DriveProgramming
function.
For the 3G3RX2 Series Inverters, it is also possible to use the analog output (current output) Ao2 terminal
as the analog output terminal variables YA(2) of the DriveProgramming function.
You can continuously monitor the status of the analog outputs regardless of the parameter settings.
To control the analog outputs via the DriveProgramming function, select DriveProgramming for the set-
ting of the inverter parameters, [FM] monitor output selection (Cd-03), [Ao1] monitor output selection
(Cd-04) and [Ao2] monitor output selection (Cd-05).
Function
variable
YA(0) FM terminal
YA(1) Ao1 terminals
YA(2) Ao2 terminals
• The analog output terminal variables YA(0) to YA(2) are unsigned 1-word variables.
