Analogue Input Adjustment (Terminal [12]) (Offset Gain Filter Gain Base Point and
Polarity Selection)
Analogue Input Adjustment (Terminal [C1]) (Offset Gain Filter Gain Base Point and
Range Selection)
Analogue Input Adjustment (Terminal [V2]) (Offset Gain Filter Gain Base Point
Polarity Selection)
For Frequency Setting, (See F01)
Setting the frequency using analog input
Gain, polarity selection, filter, and offset adjustment are possible to the analog input (voltage to be input to
terminal [12] and terminal [V2] and current to be input to terminal [C1]).

Offset (C31, C36, C41)
C31, C36 or C41 configures an offset for an analog input voltage/current. The offset of the signal from
external equipment can be also corrected.
- Data setting range: -5.0 to +5.0 (%)
Filter (C33, C38, C43)
C33, C38, or C43 sets the filter time constant for the analog input voltage/current. Choose appropriate
values for the time constants considering the response speed of the machinery system, as large time
constants slow down the response. If the input voltage fluctuates because of noise, set a large time constant.
- Data setting range: 0.00 to 5.00 (s)
Polarity selection (C35, C45)
C35 or C45 sets the input range for analog input voltage.
