Parameter Details
5
Setting 1: Combine input terminal values to create frequency reference (V1, V2, V3 are combined)
With this setting, all three input signals on the AI-A3 option card are added together to create the frequency reference.
When the option card is the source of the frequency reference for the drive, parameter b1-01 must be set to 3. Gain and
bias settings for the frequency reference supplied from AI-A3 can be set using parameters F2-02 and F2-03.

F2-02, F2-03: Analog Input Option Card Gain, Bias
Parameter F2-02 sets the gain and parameter F2-03 sets the bias for the AI-A3 input signal when the card is used in the
combined input signals mode (F2-01 = 1). Both gain and bias are set as a percentage of the maximum output frequency.
Note: Enabled only when F2-01 = 1.
 F3: Digital Input Card Settings
These parameters set up the drive for operation with the option card DI-A3. This section describes parameters that
govern operation with a digital input option card. Refer to the instruction manual packaged with the option card for
specific details on installation, wiring, input signal level selection, and parameter setup.

F3-01: Digital Input Option Card Input Selection
Determines the type of input for digital option card DI-A3 when o1-03 is set to 0 or 1.
Setting 0: BCD, 1% units
Setting 1: BCD, 0.1% units
Setting 2: BCD, 0.01% units
Setting 3: BCD, 1 Hz units
Setting 4: BCD, 0.1 Hz units
Setting 5: BCD, 0.01 Hz units
Setting 6: BCD, special setting (5 digit input), 0.02 Hz units
Setting 7: Binary
The unit and the setting range are determined by F3-03.
F3-03 = 0: 255/100% (-255 to +255)
F3-03 = 1: 4095/100% (-4095 to +4095)
F3-03 = 2: 30000/100% (-33000 to +33000)
Note: BCD input when o1-03 = 2 or 3. Units are determined by o1-03.
 F3-03: Digital Input Option DI-A3 Data Length Selection
Determines the number of bits for the option card input that sets the frequency reference.
Setting 0: 8 bit
Setting 1: 12 bit
Setting 2: 16 bit
