Bias (for PID, frequency command 2 (terminal [12])) (bias, bias base point) (refer to F01)
Bias (for PID, frequency command 2 (terminal [C1]) (C1 function))
(bias, bias base point)(refer to F01)
Bias (for PID, frequency command 2 (terminal [C1]) (V2 function))
(bias, bias base point)(refer to F01)
You can adjust the gain, bias, polarity, filter time constant and offset which are applied to analog inputs (voltage
inputs to terminals [12] and [C1] (V2 function) and current input to terminal [C1] (C1 function)).

■ Offset (C31, C36, C41)
C31, C36 or C41 configures an offset for an analog voltage/current input.
• Data setting range: -5.0 to +5.0 (%)
■ Filter time constant (C33, C38, C43)
C33, C38, and C43 provide the filter time constants for the voltage and current of the analog input. The larger the
time constant, the slower the response. Specify the proper filter time constant taking into account the response
speed of the machine (load). If the input voltage fluctuates due to line noises, increase the time constant.
• Data setting range: 0.00 to 5.00 (s)
■ Polarity Terminal [12] (C35)
C35 and C45 configure the input range for analog input voltage.
C35 data Modes for terminal inputs
0 -10 to +10 V
1 0 to +10 V (negative value of voltage is regarded as 0 V)
■ Polarity [C1] (V2 function) (C45)
C45 data Modes for terminal inputs
0 0 to +10 V
When the bias is specified to be a negative value, makes a point lower than 0
effective as a negative value.
1 0 to +10 V (factory default)
When the bias is specified to be a negative value, limits a point lower than 0 to 0.
