Polarity (C35, C45)

C35 and C45 configure the input range for analog input voltage.
Data for C35 and C45
0
1
Gain (C32, C37, C42)

To input bipolar analog voltage (0 to ±10 VDC) to terminals [12] and [V2], set C35
and C45 data to "0." Setting C35 and C45 data to "1" enables the voltage range from
0 to +10 VDC and interprets the negative polarity input from 0 to -10 VDC as 0 V.
Terminal [C1] input range selection (C40)

C40 specifies the input range of terminal [C1] (analog input current).
Data for C40
0

C53 Selection of Normal/Inverse Operation (Frequency command 1)
C53 switches the reference frequency sourced by frequency command 1 (F01) between
normal and inverse.
 For details, refer to E01 through E07 (data = 21) for the terminal command IVS
("Switch normal/inverse operation").
C55 Analog Input Adjustment for Terminal [12] (Bias value)
C55 specifies a bias value to apply to terminal [12] input of reference frequency 2, analog
input monitor and PID control input. For details, refer to the description of F01.
C56 Analog Input Adjustment for Terminal [12] (Bias base point)
C56 specifies a bias base point for Reference frequency 2 and analog input monitor terminal
[12]. For details, refer to the description of F01.
Specifications for terminal inputs
-10 to +10 V
0 to +10 V (A minus component of the input will be regarded
as 0 VDC.)
Terminal [C1] input range
4 to 20 mA (factory default)
0 to 20 mA
