9.6 Clearing Data
If data is cleared, data will revert to factory default values.
To clear data, press and hold , , , (in that order) together for approx. 3 seconds
in the PV/SV Display.
The unit enters [Data clear Yes/No] mode.
Select ‘Yes’, and press the key. Data will be cleared.
While data is clearing, is indicated in the PV Display.

9.7 2DOF PID Control
2 degrees of freedom PID control reduces overshoot or undershoot when starting control or changing
settings.
Increasing Proportional gain 2DOF coefficient (α) results in quick response, and decreasing it causes
slow response.
By increasing Integral 2DOF coefficient (β), overshoot or undershoot can be controlled more effectively.
However, response will be slower than the usual PID control for suppressing the overshoot or
undershoot.
Setting Item Set Value (or Selection)
Proportional gain 2DOF coefficient (α) 0.00 to 1.00
Integral 2DOF coefficient (β) 0.00 to 10.00
