12.7 F: Options
output voltage range of -10 V to +10 V. Install the AO-A3 card to a drive to output analog signals that monitor the
output status of the drive (output frequency and output current).
Refer to the AO-A3 card manual for more information about how to install, wire, and set the AO-A3 card.
Use the U monitor number to set the monitor data to be output from terminals V1 and V2 on the AO-A3 card. Enter
the last three digits of Ux-xx as the setting value.
• Use Gain and Bias to Adjust the Output Signal Level of Terminal V1
You must stop the drive to adjust the output signal. Use this procedure to calibrate the drive:
1. View the F4-02 [Terminal V1 Gain] value on the keypad.
Terminal V1 will output a voltage = 100% of the monitor set in F4-01 [Terminal V1 Function Selection].
2. View the monitor connected to terminal V1 and adjust F4-02.
3. View the F4-05 [Terminal V1 Bias] value on the keypad.
Terminal V1 will output an analog signal = 100% of the parameter set in F4-01.
4. View the monitor connected to terminal V1 and adjust F4-05.
• Use Gain and Bias to Adjust the Output Signal Level of Terminal V2
You must stop the drive to adjust the output signal. Use this procedure to calibrate the drive:
1. View the F4-04 [Terminal V2 Gain] value on the keypad.
Terminal V2 will output a voltage = 100% of the monitor set in F4-03 [Terminal V2 Function Selection].
2. View the monitor connected to terminal V2 and adjust F4-04.
3. View the F4-06 [Terminal V2 Bias] value on the keypad.
The analog signal equal to 0% of the parameter being set in F4-03 will be output from terminal V2.
4. View the monitor connected to terminal V2 and adjust F4-06.

Set the x-xx part of the Ux-xx [Monitors] to set monitor data to output from the option card. For example, set F4-01 =
102 to monitor U1-02 [Output Frequency].
Note:
• You cannot use all of the monitors in all of the control methods.
• When you use the terminal in through mode, set this parameter to 000 or 031. You can use MEMOBUS/Modbus communications or the
communication option to set the terminal V1 output level from the PLC.

The maximum output voltage output from terminal V1 is ±10 V. Use F4-07 [Terminal V1 Signal Level] to set the
signal level.
Example settings:
When you use these settings, and the monitored output voltage is at 100% (drive rated current), the output voltage of
terminal V1 is 5 V (50% of 10 V). The output current is 200% of the drive rated current when terminal V1 outputs a
maximum voltage of 10 V.
• F4-01 [Terminal V1 Function Selection] = 102 (U1-02: Output Frequency)
• F4-02 = 50.0%
• F4-05 [Terminal V1 Bias] = 0.0%
• F4-07 = 0 (0 V to 10 V)

Sets the monitor signal output from terminal V1.
V/f CL-V/f OLV CLV AOLV
Sets the gain of the monitor signal that is sent from terminal V1. Sets the analog signal output level
from the terminal V1 at 10 V or 20 mA as 100% when an output for monitoring items is 100%.
