7.15 Adjustment-free function (Fn200)
The adjustment-free function is a function that allows the drive to obtain a more stable response by automatic adjustment
when the mechanical type or load fluctuates.
The procedure is shown below.
Steps
Panel display
Keys used
Operations
1
Press the "MODE/SET" key to select the auxiliary function.
Adjust by pressing the "UP" and "DOWN" keys until Fn000
is displayed.
2
Adjust by pressing the "UP" or "DOWN" key until Fn200 is
displayed.
3
Press the "DATA/SHIFT" key for about 1 second and the
pole identification symbol is displayed as shown on the
left.
The "UP" and "DOWN" keys are used to select the
appropriate value according to the current load inertia.
Notes.
Change the setting to "d2" if overshoot occurs in the
response waveform, or when used on a permissible load
inertia.
When a high frequency sound occurs, change the setting
to "d0".
4
Press the "MODE/SET" key to display the rigidity value
setting screen without adjustment.
5
Press "UP" or "DOWN" to select the rigidity value.
The higher the number, the higher the gain and the higher
the response
Notes.
If the stiffness value is too high, vibration may occur, so
reduce the stiffness value.
When a high frequency sound occurs, press the
"DATA/SHIFT" button to automatically adjust the frequency
of the notch filter to the vibration frequency.
6
Press the "MODE/SET" key, the display will change to
"DonE" and flash for about 2 seconds, then "L 3" will be
displayed. The setting is saved in the servo unit.
7
Press the "DATA/SHIFT" key for about 1 second to return
to the Fn200 state.
CAUTION
●
parameter prohibition function (fn010) cannot be set to "write prohibition";
●
after the servo driver is installed on the machine, when the adjustment free function is
effective, it will send a signal when the initial servo is on. An instant sound, which is the sound
when setting the notch filter, is not a fault. After power on again, when the servo is on,No more
sound.
●
when the motor is used in excess of the allowable load moment of inertia of the motor, the
motor may produce vibration. At this point, lower the tuning Value or set mode = 2.
