Chapter 6 Parameter Description
110
2: Operational panel adjustment
∧/∨ disabled.
Thousands place: Setting of
∧/∨ on operational panel
0: With integral function. When the operation panel
∧/∨ adjustm ent is used to set the frequency, the
consistent adjustment in one direction has integral effect. The step length of adjustment starts from
0.01Hz, after every 10 times of adjustment, the step length will be increased by 10 times, and the
maximum step length of adjustment is 1.00Hz.
1: Without integral function. When the operation panel
∧/∨
adjustment is used to set the frequency, the
step length of the adjustment is fixed to 0.1Hz.
Note: When operating under process closed loop PID, the closed loop reference also can be adjusted
with operational panel
∧/∨. Then adjustm ent volum e of ∧/∨ is re
garded as analog superimposed upon
closed loop reference. The minimum step size is 1mV.

Pb.10 and Pb.11 are the same as the usage of operational panel
∧/∨. For functions of term inal
UP/DN,
refer to instructions of P5.00~P5.06.
0: No action after power resumes normal.
1: Action after power resumes normal.
The function supports automatic operation of the inverter upon power resume normal after power failure.
Be careful in using this function.
When restart after power failure is selected, the inverter will operate automatically after power on under
any operating command reference mode, such as operation panel operating command reference,
terminal operating command reference or host computer operating command reference.
When restart after power failure is selected, if P0.06=1 and the running terninal is enable when power on,
