Advanced Autotuning Procedure - YASKAWA SGDV User Manual

6.3.2 Advanced Autotuning Procedure

The following procedure is used for advanced autotuning.
The digital operator or SigmaWin+ is required to execute this function.
Σ
Refer to the -V Series User's Manual, Operation of Digital Operator (Manual No.: SIEP S800000 55) for
basic key operations of the digital operator.
• When using the SERVOPACK with Jcalc = OFF (load moment of inertia is not calculated), be sure to set a
suitable value for the moment of inertia ratio (Pn103). If the setting greatly differs from the actual moment
of inertia ratio, normal control of the SERVOPACK may not be possible, and vibration may result.
(1) Operating Procedure
Use the following procedure.

Calculating Moment of Inertia
Select the mode to be used.
Usually, set Jcalc to ON.
Jcalc = ON: Moment of inertia calculated [Factory setting]
3-1
Jcalc = OFF: Moment of inertia not calculated
Note:
If the moment of inertia ratio is already known from the machine specifications, set the value in Pn103 and set
Jcalc to OFF.
Mode Selection
Select the mode.
3-2
Mode = 1: Makes adjustments considering response characteristics and stability (Standard level).
Mode = 2: Makes adjustments for positioning [Factory setting].
Mode = 3: Makes adjustments for positioning, giving priority to overshooting suppression.
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.
3-3 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
transmissions)
