5.3 Description of Function Codes 5.3.3 C codes (Control functions)
Gain and bias
PID command, feedback, analog monitor
These are biases and bias reference 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, C82, o66, o82)
• Data setting range: -200.00 to 200.00(%)
Bias reference point (C56, C62, C68, C83)
• 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), the input value takes negative polarity with an analog
input of 0 point or lower.
