To change the setting, refer to 6.2.2 Tuning-less Levels Setting (Fn200) Procedure .
b) Using the parameter
6.2.2 Tuning-less Levels Setting (Fn200) Procedure
The procedure to use the tuning-less function is given below.
The digital operator or SigmaWin+ is required to execute this function.
For the basic operation of the digital operator, refer to Σ -V Series User’s Manual, Operation of Digital Opera-
tor (Manual No.: SIEP S800000 55).
(1) Preparation
The following conditions must be met to perform the tuning-less function. The message “NO-OP” indicating
that the settings are not appropriate will be displayed, if all of the following conditions are not met.
• 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
Use the following procedure.
Load Level Meaning
Mode 0 Load level : Low
Mode 1 [Factory setting] Load level : Medium
Mode 2 Load level : High
Parameter Meaning When Enabled Classification
Pn170
n.0 Load level : Low (Mode 0)
Immediately Setup
n.1
[Factory setting]
Load level : Medium (Mode 1)
n.2 Load level : High (Mode 2)
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.
