NSOLL_A
NSOLL_A is the reference to the drive. It is used normally as Speed reference. Reference is a 16-bit
word containing a sign bit and a 15-bit integer. A negative reference (indicating reversed direction of
rotation) is formed by calculating the two’s complement from the corresponding positive reference.
The allowed scaling is –10000...10000. In the drive application, the value is scaled in percentage of
the frequency area between set minimum and maximum frequency.
-10000 = 100,00 %
(Direction reverse)
0 = 0, 00 %
(Direction forward)
10000 = 100,00 %
(Direction forward)
5.3.1.4.
NIST_A
NIST_A is the actual value from the frequency converter. It contains values between -10000...10000.
In the application, the value is scaled in percentage of frequency area between set minimum and
maximum frequency.
-10000 = 100,00 %
(Direction reverse)
0 = 0, 00 %
(Direction forward)
10000 = 100,00 %
(Direction forward)
