1  If you return to the initial screen using the                 key, the excessive deviation error will be 
indicated because a deviation can be left on the controller in this manner.     
This alarm, however, is not recorded in the alarm history. 
•  Clear the alarm before starting normal operation of the remote controller. 
•  You can suppress the excessive deviation alarm by setting parameter Func6 bit4 to 1.

7.1.9.2  Offline automatic tuning function 
●  Outline of offline automatic tuning function 
The offline automatic tuning function operates the motor through the remote operator and estimates load 
inertia from its operating status.    With this, proper parameters are automatically set.    Four parameters 
for position loop gain (Kp), velocity loop proportional gain (Kvp), velocity loop integral time constant (Tvi) 
and current command LPF (ILPF) are set using this...

●   Outline of Automatic notch filter tuning function (Tune IBEF) 
The automatic notch filter tuning function operates the motor through the remote operator and estimates 
resonance point of current loop from its operating status, and proper parameters are automatically set 
as notch filter frequency.    Current command BEF1 parameter (IBF1) is set using this function.

7.1.9.4  Automatic offset function 
●  Outline of automatic offset function 
This function enables an offset value for a velocity or torque command to be automatically selected.   
It implements velocity command zero adjustment (Vzero) or torque command zero adjustment 
(Tzero)

• VCMD → TCMD. 
An ideal zero adjustment may not be expected if significant fluctuation exists in the 
commanded input voltage or substantial noise is present....
