Yaskawa Sigma-II Large Capacity - Manual (Page 2)

1. Notes on Application
Notes Check Item
Usage condition in ∑-II Usage of ∑-V
Using S-phase output of absolute
encoder
S-phase output is not available in
SGDV. There are no alternatives.
Please use the multi-turn data and
initial incremental pulse. Or, please
read data through PC communication
(RS-422).
Using reference input magnification
function
The reference input magnification
function is not available in SGDV. There
are no alternatives. Switch by a host
controller or MECHATROLINK
communication.
Using auto tuning function The same auto-tuning function as Σ-II is
not provided in SGDV. The tuneless
function is the alternative function.
Please use the advanced auto-tuning
function or moment of inertia
identification function of SigmaWin +
when you need to know the moment of
inertia ratio.
Using speed bias function The speed bias function is not provided
in SGDV. The positioning time can be
shortened by using "Positioning setting
(model following control)" of the
advanced auto-tuning function.
Using auto gain switch function The auto-gain function is not provided
in SGDV. There are no alternatives.
Please switch by using C-SEL signal in
a host controller or MECHATROLINK
communication.
Using SGDM/SGDH Type
Servo Amplifier
Using duct ventilation type Please inquire to the factory. Although
there is a model that corresponds to the
duct ventilation type but the capacity is
limited and the installation size is
different.
Using Application Module None N/A
