4) Interpolation output value
The interpolation operation value that is currently being outputted can check in parameter
area (Address No. 17 ~ 20) while using interpolation function.

5) Interpolation flag turns on while the interpolation is outputted. And when the interpolation
output value is reached at objective value, It will turn off.

Channel 3 interpolation output in operation
6) Example
The output is changed from 4mA to 20mA and then when it is reached at 20mA, if the output
comes back 4mA again, you have to do as follows.

Notes
1) During the interpolation output, If the internal parameter is changed, the interpolation operation will
be temporarily stopped and the output can be immediately changed to objective value.
2) If the change of internal parameter is needed, change the parameter during interpolation output
after the flag turns off when the analog output value is not changed.
