17.1.9 J3 extension function
POINT
The J3 extension function is used with servo amplifiers with software version B0
or later.
To enable the J3 extension function, MR Configurator2 with software version
1.25B or later is necessary.
The J3 extension function of the amplifier differs from MR-J3-B in motion.
The J3 extension function is for using functions of J4 mode with J3 compatibility mode.
By enabling the J3 extension function, you will get control response which is equal to MR-J4 series using a
controller compatible with SSCNET III.

Function Description
Detailed
explanation
Gain switching function
(Vibration suppression control
2 and model loop gain)
You can switch gains during rotation/stop, and can use input devices to switch gains
during operation.

17.1.9 (6)
Advanced vibration
suppression control II
This function suppresses vibration at the arm end or residual vibration.
Section
17.1.9 (5) (c)
Machine resonance
suppression filter 3
Machine resonance
suppression filter 4
Machine resonance
suppression filter 5
This is a filter function (notch filter) which decreases the gain of the specific frequency
to suppress the resonance of the mechanical system.
Section
17.1.9 (5) (a)
Shaft resonance suppression
filter
When a load is mounted to the servo motor shaft, resonance by shaft torsion during
driving may generate a mechanical vibration at high frequency. The shaft resonance
suppression filter suppresses the vibration.
Section
17.1.9 (5) (b)
Robust filter
This function provides better disturbance response in case low response level that
load to motor inertia ratio is high for such as roll send axes.

One-touch tuning
Gain adjustment is performed just by one click on a certain button on MR
Configurator2.
MR Configurator2 is necessary for this function.
Section
17.1.9 (4)
Tough drive function
This function makes the equipment continue operating even under the condition that
an alarm occurs.
The tough drive function includes two types: the vibration tough drive and the
instantaneous power failure tough drive.
Section
17.1.9 (7)
SEMI-F47 function (Note)
Enables to avoid triggering [AL. 10 Undervoltage] using the electrical energy charged
in the capacitor in case that an instantaneous power failure occurs during operation.
Use a 3-phase for the input power supply of the servo amplifier. Using a 1-phase 200
V AC for the input power supply will not comply with SEMI-F47 standard.
