6.5.2 One-parameter Tuning Procedure
The following procedure is used for one-parameter tuning.
Operation procedures will vary in accordance with the tuning mode being used.
• When the tuning mode is set to 0 with priority given to stability or when the tuning mode is set to 1 with pri-
ority given to responsiveness, refer to (1) Setting the Tuning Mode to 0 or 1.
• When the tuning mode is set to 2 or 3 for adjustments in positioning, refer to (2) Setting the Tuning Mode to
2 or 3.
One-parameter tuning is performed from the Digital Operator (option) or SigmaWin+.
Mode 2 and mode 3 cannot be selected from the Panel Operator.
To perform one-parameter tuning with mode 2 or mode 3, operate from the Digital Operator or SigmaWin+.
The operating procedure from the Digital Operator is described here.
Refer to the
Σ
-V series User’s Manual, Operation of Digital Operator (SIEP S800000 55) for basic key oper-
ations of the Digital Operator.

Press the Key to display the moment of inertia
ratio set in Pn103 at present. Select the digit with the
or Key, change the set value with the
or Key.
Note: If the display does not switch and NO-OP is
displayed, refer to 6.5.1 (1) Before Performing

steps 4-1 and 4-2.
4-1
Tuning Mode
Select the tuning Mode. Select the tuning mode 0 or 1.
Tuning Mode = 0: Makes adjustments giving priority to stability.
Tuning Mode = 1: Makes adjustments giving priority to responsiveness.
Tuning Mode = 2: Makes adjustments for positioning.
Tuning Mode = 3: Makes adjustments for positioning, giving priority to overshooting suppression.
4-2
Type Selection
Select the type according to the machine element to be driven.
If there is noise or the gain does not increase, better results may be obtained by changing the rigid type.
Type = 1: For belt drive mechanisms.
Type = 2: For ball screw drive mechanisms [Factory setting].
Type = 3: For rigid systems, such as a gear.
5
Input an external /S-ON signal. The display will
change from "BB" to "RUN." Input a reference from
the host controller.
