6. NORMAL GAIN ADJUSTMENT
6 - 32
6.5 2 gain adjustment mode
Use the 2 gain adjustment mode to match the position loop gains of the axes when performing the
interpolation operation of servo motors of two or more axes for an X-Y table or the like. In this mode,
manually set the model loop gain that determines command trackability. Other parameters for gain
adjustment are set automatically.
(1) 2 gain adjustment mode 1
For the 2 gain adjustment mode 1, manually set the model loop gain that determines command
trackability. The mode constantly estimates the load to motor inertia ratio, and automatically set other
parameters for gain adjustment to optimum gains using auto tuning response.
The following parameters are used for 2 gain adjustment mode 1.
(a) Automatically adjusted parameter
The following parameters are automatically adjusted by auto tuning.

(2) 2 gain adjustment mode 2
Use 2 gain adjustment mode 2 when proper gain adjustment cannot be made with 2 gain adjustment
mode 1. Since the load to motor inertia ratio is not estimated in this mode, set the value of a proper load
to motor inertia ratio in [Pr. PB06].
The following parameters are used for 2 gain adjustment mode 2.

The following parameters are automatically adjusted by auto tuning.
