Set values when using internal speed references using digital speed refer-
ences. The correspondence with reference inputs (1CN) are as shown
below, and are given as percentages over the rated speed (C1-26).

Pin 20: SPD2
Pin 21: SPD3
Pin 22: SPD4
Set value of the analog speed reference read gain in servo mode. (En-
abled when C1-38 bit 3 is ON and C1-40 bit 5 is ON.) Set the ratio of the
number of rotations when the analog speed reference is 10 V over the
rated speed (C1-26).
A l Analog speed reference 10 V/(S100 x SVGAIN/100) min
Select C1-49 and C1-50 using the DAS signal (C6N-5).
DAS = OFF: C1-49 (SVGAIN1)
DAS = ON: C1-50 (SVGAIN2)

Offset adjustment value for speedometer signal. Outputs speedometer
signal after subtracting from SM signal after subtracting from SM
Offset adjustment value for load meter signal. Outputs speedometer
signal after subtracting from LM signal after subtracting from LM
