FB tuning
Starts/checks/forcibly terminates FB auto tuning.
The result of FB tuning is stored in the following parameters automatically.
• Feedback zero (MODE6)
• Feedback span (MODE6)

This display is available for the ON-OFF servo output type.
Set FB tuning by using the [

], [

] and [ENT] keys.
FB tuning cannot start when "MANUAL output" is selected at "AUTO/MANUAL
output switch (operation screen)".
FB tuning will be forced to terminate when the power is turned OFF during the
execution of FB tuning. FB zero/span value will not be calculated automatically.
If a measured value error (±over range) occurs during FB tuning, a PV abnormal
output may be made, preventing normal completion of the FB tuning.
* Make sure to execute FB tuning immediately after initial power-ON and parameter
initialization.
[Switch to operation initial screen]
Press and hold the [MODE] key to display the screen set on the MODEt operation

READY status
Set RUN or READY using the [

], [

] and [ENT] keys.
[RUN status]
Normal control status
Operation performed when the status is switched from READY to RUN
•The PV start operation is executed according to the setting of "SV
rate-of-change (MODE1)" and PV start for constant value operation (MODE1)
•The balance less bump less operation (suppresses rapid change in output) is
performed for the output.
[READY status]
"Preset manual (MODE6, MODE7)" will be output. Note that the control calculation
is continued.
Turning ON/OFF an alarm event follows the setting of "Alarm action at READY
(MODE1)".
[Switch to operation initial screen]
Press and hold the [MODE] key to display the screen set on the MODEt operation
initial screen.
[AUTO/MANUAL output switch]
Press and hold the [>] key to switch the output between AUTO and MANUAL.
