Parameter Scaling
A real value of a parameter measured or sensed through feedback circuitry
can be calculated from the channel register value, in Q15 format, and the
Full Scale Value as follows:
1. V
real
= (V
Q15
/2
15
) * V
FSV
2. V
real
= [(V
Q15
- 2
16
)/2
15
] * V
FSV
For HEX value, of a parameter, ≤ 7FFF (means positive value) use equation
(1).
For HEX value, of a parameter, > 7FFF (means negative value) use equation
(2).
▪ Example 1: DC link Voltage channel reads 50A1 which is ≤ 7 FFF
(positive value) then apply equation (1).
Decimal value of 50A1 HEX is 20641, so
DC link Voltage
real
= (20641/2
15
)* 500 = 314.95 V where 500 is the Full
Scale Value, V
FSV
, of the Voltage.
▪ Example 2: Motor Current channel reads E0C1 which is > 7 FFF
(negative value) then we apply equation (2).
Decimal value of E0C1 HEX is 57537, so
Motor Current
