SV026
OD2
Excessive error detection
width at servo OFF
A protective function will activate if the error between the position command and
position feedback is excessive. If the machine load is heavy and problems
occur with the standard settings, gradually increase the setting value.

9-2-3 Parameters set according to machine movable mass
The following parameters are set according to the machine's movable mass (including motor mass).

Explanation
SV005
VGN1
Speed loop gain.
Refer to the comparison graph with the total movable mass (including motor
mass) for the standard setting value.
SV008
VIA
Speed loop leading
compensation
Set 1364 as a standard. Set 1900 as a standard for the SHG control.
If the total movable mass is large and the VGN1 value is smaller than the
standard value, a lower value can be set regardless of whether normal control
or SGH control is used.
