Operational panel ∧/∨ digital regulating frequency control
Pb.08
Pb.09
Through operational panel ∧T∨ to regulate frequency and the frequency value will be saved and
superimposed on other frequency as final frequency.
The parameter Pb.08 determines the function of operation panel ∧/∨.
The parameter Pb.09 is used to set the time that refresh frequency increment or decrement for one time
when adjusting with ∧/∨continuous.
Pb.08 ones place is used to set whether save the incremental part regulating by operational panel ∧T∨
after power off
0: Saved after power-off
T: Cleared after power-off
Pb.08 tens place is used to set whether save the incremental part regulating by operational panel ∧T∨
after stop.
0: Saved in stop status
T: Cleared after receive a stop command
T: Cleared in stop status
Pb.08 hundreds place is used to set when the operational panel ∧T∨ regulating function is activated.
0: Only active when the frequency reference is P0.05 (P0.04=0)
T: Always active
T: Always inactive
Pb.08 thousands place is used to activated the operational panel ∧T∨ regulating integral function.
0: With integral function. When the operation panel ∧/∨ adjustment is used to set the frequency, the
consistent adjustment in one direction has integral effect. The step length of adjustment starts from
0.0THz, after every T0 times of adjustment, the step length will be increased by T0 times.
T: Without integral function. When the operation panel ∧/∨ adjustment is used to set the frequency, the
step length of the adjustment is determined by parameter Pb.06.
Note:
For process closed loop PID, the closed loop reference also can be adjusted by operational panel ∧/∨.
Then adjustment value of ∧/∨ is regarded as analog superimposed on the closed loop reference. The
minimum step length is TmV.
