Using S-phase output of absolute
encoder
S-phase output is not available in
SGDV. There are no alternatives.
Using auto tuning function
The same auto-tuning function as Σ 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.
The main circuit power supply input
terminal and control power supply
input terminal are common in the
SGD/SGDA series
The main circuit power supply input
terminal and control power supply input
terminal are separated. Please
confirm the method of power activation.
Using SGD(A)-
S (speed・torque
control type)
There is no distinction between the
speed torque control type and
positional control type in SGDV. It is
possible to use either control type.
Using SGD/SGDA/SGDB
Type Servo Amplifier
Using SGD(A)-
P (position
control type)
There is no distinction between the
speed torque control type and
positional control type in SGDV. It is
possible to use either control type.
