Chap. 9 FUNCTION CODES
C32 Analog Input Adjustment for [12] (Gain) F18 (Bias, Frequency command 1)
Refer to the description of F18.
C33
Analog Input Adjustment for Terminal [12] (Filter time constant)
C38 (Analog Input Adjustment for Terminal [C1], Filter time constant)
C33 and C38 configure a filter time constant for an analog voltage and current input on
terminals [12] and [C1], respectively.
• Data setting range: 0.00 to 5.00 (s)
• 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 noise, remove the cause of the noise or take an electric circuit related measure.
Only when no effect is obtained, increase the time constant.
C34
Analog Input Adjustment for [12] (Gain base point)
F18 (Bias, Frequency command 1)
Refer to the description of F18.
C37
Analog Input Adjustment for Terminal [C1] (Gain)
F18 (Bias, Frequency command 1)
Refer to the description of F18.
C38
Analog Input Adjustment for Terminal [C1] (Filter time constant)
C31 (Analog Input Adjustment for Terminal [12], Offset)
Refer to the description of C31.
C39
Analog Input Adjustment for Terminal [C1] (Gain base point)
F18 (Bias, Frequency command 1)
Refer to the description of F18.
C40
