8-5. Change in position of decimal point
Position of decimal point can be changed for linear input and for TC and RTD range with decimal point.
You should keep in mind that operation differs for TC and RTD range when using linear input.
(1) Change in position of decimal point for linear input
Sets position of decimal point to be displayed.
If changing position of decimal point from 0.0 to 0.000, input scaling changes from 0.0–100.0 to 0.000–1.000.
(2) Change in position of decimal point of TC/RTD range
Display of places below the decimal point can be switched to display or mask.
If changing position of decimal point from 0.0 to 0, the places below the decimal point are rounded off before being masked.
If changing position of decimal point from 0 to 0.0, the places below the decimal point are displayed again.
Things requiring special attention:
Ɣ Parameter values affected by range change (digit) also change similarly.
 Example: If range is “4” (PV bias)

[Position of decimal point: 0.0] Ѝ Change Ѝ [Position of decimal point: 0] Ѝ Change again Ѝ [Position of decimal point: 0.0]
 Measuring range lower limit value: -199.9  -200  -199.9
 Measuring range higher limit value:  400.0  400  400.0
 PV bias: 20.5  21  21.0
 Note: As described above, after changing the position of the decimal point, the value may not revert to the original value
 when the position of the decimal point is changed back.
Ɣ When measurement range is changed, the position of the decimal point returns to the default position.
Ɣ If position of decimal point is 0, display accuracy is not guaranteed.
8-6. Start SV
When the start step of the program operation is controlled by ramp control, if the start SV value greatly differs from PV value,
the action time may be wasted. To prevent this, the start SV value may conform to the PV value when starting the operation.
(1) When start SV function is invalid
When PV value does not fall between start SV value (SSV) and target step 1 SV value (SV1)
(2) When start SV function is valid
When PV value falls between start SV value (SSV) and target step 1 SV value (SV1)
(3) When start SV function is valid and start step is skipped
When PV value exceeds target step 1 SV value (SV1)
