7-3 Description of Functions
Input/Output-Related Function
The function blocks of input and output terminals of the inverter control circuit are described as follows.
F1401 Bias frequency (VIF1)
F1402 Gain frequency (VIF1)
F1403 Bias frequency (VIF2)
F1404 Gain frequency (VIF2)
F1405 Bias frequency (VIF3)
F1406 Gain frequency (VIF3)
In case of setting output frequency using the analog signal, these functions are used to set a frequency (bias frequency)
corresponding to minimum analog signal value (0V or 4mA) and a frequency (gain frequency) corresponding to
maximum value (5V or 10V and 20mA).

Setting example: When F1401 =- 10.0 (-10Hz), F1402 = 90.0 (90 Hz), and F1002 = 3 (frequency setting VIF1: 0 - 10V),
the output frequency is as shown below.
