To get the most accurate data from the analog interface, the user must calculate gain and offset. Then the
user must change the parameters of the Inverter. The symbols for gain and offset are listed here:
M
l
: lower limit of analog input by sensor.
M
u:
upper limit of analog input by sensor.
D
l
: lower limit of displayed value.
D
u
: upper limit of displayed value.
M: input value in range of M
l
and M
u
.
D: displayed value in range of D
l
and D
u
.
Gain: G= (D
u
–D
1
) / (M
u
– M
1
)
Offset: O = D
1
– (G x M
1
)
Displayed value: D = (G x M) + O
After calculating gain and offset, the user must change the values through the GUI or use the CMT (change
the settings in the analog tab located in parameter panel).
CAUTION!
Voltages > 10Vdc or reversed polarity may lead to damage of the sensor input circuits
IMPORTANT!
System will show unexpected values if gain and offset are not properly set. Ensure that
calculations are exact.
