Setting Procedure (Example: DeviceNet Configurator)
1,2,3...
Note Reverse scaling, where the 0% scaling value is higher than the 100% scaling
value, is also supported.
Offset compensation is used to compensate for error that occurs during scal-
ing. The offset amount is added to the scaled line before processing, as
shown in the following diagram. The offset (error) value can be input between
28,000 and 28,000, but if underflow or overflow occurs in the scaled line, the
–
100% or 0% output will not be possible. The High Limit is 7FFE hex and the
Low Limit is 8000 hex.
Note The offset value can be set even when using default scaling.
Upper limit 7FFE
