5 Basic Settings
Using Sum of Multiple Analog Inputs
To use a sum of multiple analog inputs to set the frequency reference, set the parameters as follows.
This enables the sum of three analog inputs to the frequency reference input (voltage reference),
frequency reference input (current reference), and auxiliary frequency reference input (Voltage
reference) terminals to be set as the frequency reference inverter.
In the FE Selection (A006), set the operation to be performed if the sum of these three analog inputs is
negative.
• 01: FV/FI auxiliary frequency reference (not reversible)
The frequency is limited to 0 Hz, and the motor does not rotate in reverse direction to the RUN
command.
• 02: FV/FI auxiliary frequency reference (reversible)
The motor rotates in a reverse direction to the RUN command.

• Frequency reference input (Voltage reference), between terminal FV and FC: 0 to 9.8 VDC
• Frequency reference input (Current reference), between terminal FI and FC: 4 to 19.8 mA
• Auxiliary frequency reference input (Voltage reference), between terminal FE and FC: –9.8 to 9.8
VDC
Note By default, each analog input signal is set to reach the maximum frequency at 9.8 V or 19.8 mA.
