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 (optional), or SigmaWin+.
For the basic operation of the digital operator, refer to
Σ
-V series User’s Manual, Operation of Digital Opera-
tor (SIEP S800000 55).
(1) Before Performing Tuning-less Function
Check the following settings before performing the tuning-less function, or otherwise "NO-OP" will be dis-
played during the tuning-less operation.
• The tuning-less function must be enabled. (Pn170.0 = 1)
• The write prohibited setting (Fn010) must not be set.
(2) Operating Procedure with Digital Operator
CAUTION
To ensure safety, always implement the tuning-less function in a state where an emergency stop is possible.
Step Display after Operation Keys Operation
1
Press the Key to view the main menu for the
utility function mode.
Use the or Key to move through the list,
select Fn200.
2
Press the Key to display the tuning-less mode
setting screen.
Notes:
• If the display does not switch and NO-OP is dis-
played, the write prohibited setting is set in Fn010.
Change the setting in Fn010 and press the key
again after enabling writing.
• 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 to the mode setting to 0.
• The tuning mode can be also changed in Pn170.3.
3
Press the Key to display the tuning level setting
screen.
4
Press the or Key to select the tuning level.
Select the tuning 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 tuning level is too high.
Lower the tuning level if vibration occurs.
• If a high-frequency noise is heard, press the
Key to automatically set a notch filter for the vibra-
tion frequency.
• The tuning mode can be also changed in Pn170.2.
5
Press the Key. "Done" will blink and the settings
will be saved in EEPROM.
