The 3E Model has a speed frequency response
of 2.2 kHz, approximately twice that of our con-
ventional product. Additionally, the position
settling time has been shortened to 1/3 of the
original time. A function for switching between
trajectory control and positioning control in real
time has been incorporated to significantly re-
duce the cycle time of your machines.

The 3E Model is equipped with a gain increase
function, a function for suppressing microvi-
brations at settling time, an adaptive notch
filter for suppressing mechanical resonance,
and a feed-forward vibration control function.
This 5th-order notch filter can precisely control
the feed shaft of machine tools, significantly
improving the processing quality.
Built-in safety functions
The servo amplifier lineup includes SafeTorque Off (STO) function models,(1) and functional safety models(2) that
provide extended safety functions. The functional safety models feature monitoring of position and speed of
machines as well as safe stop so that workers nearby can concentrate on their work with confidence.
With these safety functions, motors can be stopped without shutting down the amplifier power, shortening the
machine reboot time. These products are suitable for machines that require high levels of safety.
(1) SafeTorque Off (STO) is a safety function defined in IEC/EN 61800-5-2:2016.
(2) In addition to STO,(1) the followings are also featured: SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operating Stop), SLS (Safely-Limited Speed), SBC (Safe
Brake Control), and SSM (Safe Speed Monitor).
