5.3 Description of Function Codes
5-146
■ Gain/bias
Terminal PID command, feedback, analog monitor
[12]
[C1] (C1 function)
[C1] (V2 function)
These are biases and bias base points used for PID command, PID feedback, frequency command 2 and analog
monitor. For details, refer to the description of F01 and J01.
Bias (C55, C61, C67)
• Data setting range: -100.00 to 100.00 (%)
Bias base point (C56, C62, C68)
• Data setting range: 0.00 to 100.00 (%)
Specifying the bias as a negative value allows an input to be specified as bipolar for a unipolar analog input. By
setting C40 data to 10 or 11 for terminal [C1] (C1 function) or C45 data to 1 for terminal [C1] (V2 function), an input
value for an analog input equal to or lower than 0 point is specified to have negative polarity.
C50
Bias (Frequency setting 1) (Bias base point) (refer to F01)
Refer to the description of F01.
C53
Selection of normal/inverse operation (frequency setting 1)
Switches between the between normal and inverse operation of frequency setting 1 (F01) .

For details, refer to E01 through E05 (data = 21) for the terminal command IVS (“ Switch normal/inverse
operation – “IVS””).
