Σ-7 Tuning-less
Ultimate Usability
Bologna, 10 marzo 2015
No gain adjustment! Yaskawa’s original tuning-less function has developed further
in efficiency and usability!
Conventional case
Solution
Vibration arises,
though servo tuning
is awkward…
With tuning-free function, you
can get:
· smooth device runs at
maximum load-inertia ratio
30 (equivalent to speed loop
gain 70Hz)
Creaking noise!

Running

· stable operations even if
load varies

High stability, no

(at load-inertia ratio 30)
Bologna, 10 marzo 2015
Σ-7 Series Tunning-less
Control
Tuning-less control is improved
When the inertia moment ratio is less than 30, tuning-less control can suppress the vibration even if the
load varies.
It is especially effective for trial operation where response is not required.
Σ-7 amplifier provides higher gain of tuning-less control than that of Σ-V.
Settling time is shortened by around 50%!

Vibration Suppressing
Function of Σ-7 Series
Usually, machine vibration gets worse when the axes moves at high acceleration.
Σ-7 servo enhances the vibration suppressing function to help reduce the vibration much
more than the previous products.
•
Notch filter
Suppresses vibration at high frequencies of over 500Hz
Σ-V: Two filters → Σ-7: Five filters
•
Anti-resonance function
Suppresses vibration at frequencies from several hundred Hz to 1kHz
Σ-V: Suppression at one frequency → Σ-7: Suppression at two frequencies
•
Vibration suppressing function
Suppressing low frequencies under several tens Hz
Σ-V: Suppresses vibration at one frequency → Σ-7: Suppresses vibration at two frequencies
In addition, auto-tuning function can automatically adjust the above functions.
Bologna, 10 marzo 2015
Σ-7 Friction Model
Compensation Function
Effective for preventing falling when operation starts and suppressing
vibration of a low-rigidity machine.
•
User can specify the friction coefficient of the mechanism system directly.
•
This function can compensate the coulomb friction, viscosity friction and external force like gravity of a
mechanical system.
•
Unlike the Σ-V’s friction compensation function (called as “disturbance observer”), the new function of
Σ-7 has no correction delay since it compensates the friction of the mechanism system. Hence, it can
be expected to effectively prevent falling at the start of operation and suppress the vibration of a low rigidity machine.
Bologna, 10 marzo 2015
Σ-7 Series Ripple
Compensation Function
Effective for reducing the speed ripple caused by motor cogging even if the
machine has low-rigidity and high speed loop gain cannot be increased.
•
User can specify the friction coefficient of the
mechanism system directly.
•
This function can compensate the coulomb friction,
viscosity friction and external force like gravity of a
mechanical system.
•
Unlike the Σ-V’s friction compensation function (called
as “disturbance observer”), the new function of Σ-7 has
no correction delay since it compensates the friction of
the mechanism system. Hence, it can be expected to
effectively prevent falling at the start of operation and
suppress the vibration of a low-rigidity machine.

per unit time and total energy consumption for every Servo pack,
and displays the energy consumption in driving the entire device in
the unit that the user specifies.
