1.6 Functions
Function Description Reference
High-resolution encoder Motor encoder has a resolution of 131072 pulses/rev. —
Absolute position detection
system
Merely setting a home position once makes home
position return unnecessary at every power-on.
Chap. 6
Adaptive vibration suppression
control
Servo amplifier detects mechanical resonance and
sets filter characteristics automatically to suppress
mechanical vibration.
Section 5.1.2
Vibration suppression control Vibrations with an amplitude of ±1 impulse on stopping
the servo motor are suppressed.
Parameter 24
Low-pass filter Suppresses high-frequency resonance which occurs
as servo system response is increased.
Section 5.1.3
Machine analyzer function By attaching the MR-J2-Super to a PC on which the
setup software is installed, the frequency
characteristics of the mechanical system can be
recorded.
—
Machine simulation Can simulate machine motions on a personal computer
screen on the basis of the machine analyser results.
—
Gain search function Personal computer changes gains automatically and
searches for overshoot-free gains in a short time.
—
Real-time auto tuning Automatically adjusts the gain to optimum value if load
applied to the servo motor shaft varies.
This function is more powerful on the MR-J2-Super
than on the MR-J2.
Section 4.6.3
Analog monitor output Servo status is output in terms of voltage in real time. Parameter 22
Torque limit Servo motor torque can be limited to any value. Parameter 10, 11
Forced stop The external EMERGENCY OFF signal (EM1) can be
released internally.
Parameter 23
Forced output signal Output signal can be forced on/off independently of the
servo status.
Use this function for output signal wiring check, etc.
Section 4.4
Test operation mode The servo motor can be operated from the servo
amplifier without a start signal.
Section 4.4
Regenerative brake option Used when the built-in regenerative brake resistor of
the servo amplifier does not have sufficient
regenerative capability for the regenerative power
generated.
Section 7.1.1
Setup software Using a personal computer, parameter setting, test
operation, status display, etc. can be performed.
