5.3.2 Frequency set-point/ Actual frequency

The data format is “Standardized value”, where 0 hex = 0 % and 4000 hex is 100% of Maximum frequency

specified in parameter A004. Standardized value

A linear value.

0%=0 (0h), 100% is 214 (4000h)

Data type	N2
Range	-200%…200%-2-14
Resolution	2-14= 0.0061%
Length	2 bytes
Notation:	2’s complement notation.
	MSB is 1st bit after sign bit in 1st byte.
	Sign bit = 0 = positive number
	Sign bit = 1 = negative number
Bit	8	7	6	5	4	3	2	1
Byte 1	SIGN	20	2-1	2-2	2-3	2-4	2-5	2-6
