6.2.2 Tuning-less Levels Setting (Fn200) Procedure
The procedure to use the tuning-less function is given below.
Operate the tuning-less function from the panel operator, digital operator (option), or SigmaWin+.
For the basic operation of the digital operator, refer to Σ -V Series User’s Manual, Operation of Digital Opera-
tor (No.: SIEP S800000 55).
(1) Preparation
Check the following settings before performing the tuning-less function. If the settings are not correct, "NO-
OP" will be displayed during the tuning-less function.
• The tuning-less function must be enabled (Pn170.0 = 1).
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
• The test without a motor function must be disabled. (Pn00C.0 = 0).
(2) Operating Procedure with Digital Operator
CAUTION
• To ensure safety, perform the tuning-less function in a state where the SERVOPACK can come to an
emergency stop at any time.
Step Display after Operation Keys Operation
1
Press the Key to view the main menu for the
utility function.
Use the
or Key to move through the list,
select Fn200.
2
Press the Key to display the load level of the
tuning-less mode setting screen.
Notes:
• If the response waveform causes overshooting or if
the load moment of inertia exceeds the allowable
level (i.e., outside the scope of product guarantee),
press the
Key and change the mode setting to
2.
• If a high-frequency noise is heard, press the
Key and change the mode setting to 0.
3
Press the Key to display the rigidity level of the
tuning-less mode setting screen.
4
Press the Key or the Key to select the rigid-
ity level.
Select the rigidity level from 0 to 4. The larger the
value, the higher the gain is and the better response
performance will be. (The factory setting is 4.)
Notes:
• Vibration may occur if the rigidity level is too high.
Lower the rigidity level if vibration occurs.
• If a high-frequency noise is heard, press the
Key to automatically set a notch filter to the vibra-
tion frequency.
5
Press the Key. “DONE” will flash for approxi-
mately two seconds and then “RUN” will be dis-
played. The settings are saved in the SERVOPACK.
