5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
If bipolar (terminal [12] (C35 = 0), terminal [V2] (C45 = 0), terminal [C1] (V3 function) (C78 = 0))
For terminal [12], [V2], and [C1] (V3 function), by setting function codes C35, C45, and C78 to “0”, it is possible to
use bipolar input (-10 to +10 V).
When both bias (F18) and bias reference point (C50) are set to “0”, command becomes forward and reverse
symmetric as shown in the diagram below.
• When bias (F18) and bias reference point (C50) is set to arbitrary value (A1 point, A2 point, and A3
point, etc.), as shown in the diagram below, it is determined by the bias value (F18).
• To input bipolar (0 to ±10 VDC) analog voltage by analog input, set function codes C35, C45, and C78
to “0”. When the C35, C45, and C78 data is “1”, only 0 to +10 VDC effective and negative polar input
0 to -10 VDC regarded as 0 (Zero) V.
• When setting reference frequency by display other than frequency (Hz), please change the speed
monitor unit in E48.
