One-Parameter Tuning Procedure - YASKAWA SGDV series User Manual

5.5.2 One-parameter Tuning Procedure

The following procedure is used for one-parameter tuning.
There are the following two operation procedures depending on the tuning mode being used.
• When the tuning mode is set to 0 or 1, the model following control will be disabled and one-parameter tun-
ing will be used as the tuning method for applications other than positioning.
• When the tuning mode is set to 2 or 3, the model following control will be enabled and it can be used for
tuning for positioning.
One-parameter tuning is performed from the digital operator (option) or SigmaWin+.
Make sure that the moment of inertia ratio (Pn103) is set correctly using advance autotuning before beginning
operation.
The following section provides the operating procedure from the digital operator.
Σ
Refer to the -V Series User's Manual, Operation of Digital Operator (No.: SIEP S800000 55) for basic key
operations of the digital operator.

Tuning Mode
Select the tuning mode. Select the tuning mode 0 or 1.
4-1
Tuning Mode = 0: Makes adjustments giving priority to stability.
Tuning Mode = 1: Makes adjustments giving priority to responsiveness.
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 rigidity type.
4-2
Type = 1: For belt drive mechanisms
Type = 2: For ball screw drive mechanisms [Factory setting]
Type = 3: For rigid systems in which the servomotor is directly coupled to the machine (without gear or other
5
transmissions).
