1. FUNCTIONS AND CONFIGURATION
1.4 Function list
The following table lists the functions of this servo. For details of the functions, refer to the reference field.
Function Description Reference
High-resolution encoder
High-resolution encoder of 262144 pulses/rev is used as a servo motor
encoder.
Absolute position detection
system
Merely setting a home position once makes home position return
unnecessary at every power-on.
Gain changing function
You can switch between gains during rotation and gains during stop or use
an external signal to change gains during operation.
Advanced vibration
suppression control
This function suppresses vibration at the arm end or residual vibration.
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Low-pass filter
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Refer to the MR-J3-
B Servo Amplifier
Instruction Manual.
Machine analyzer function
Analyzes the frequency characteristic of the mechanical system by simply
connecting a MR Configurator-installed personal computer and servo
amplifier.
MR Configurator is necessary for this function.
Machine simulation
Can simulate machine motions on a personal computer screen on the basis
of the machine analyzer results.
MR Configurator is necessary for this function.
Gain search function
Personal computer changes gains automatically and searches for overshoot-
free gains in a short time.
MR Configurator is necessary for this function.
Robust disturbance
compensation
This function provides better disturbance response in case of low response
level due to high load inertia moment ratio for the roll send axes.
MR Configurator is necessary for this function.
Advanced Gain search
Advanced Gain search automatically searches for the optimum parameter for
settle time to be short.
The gain can be adjusted by setting sequentially in accordance with wizard
screens.
MR Configurator is necessary for this function.
Slight vibration suppression
control
Suppresses vibration of
1 pulse produced at a servo motor stop.
Auto tuning
Automatically adjusts the gain to optimum value if load applied to the servo
motor shaft varies. Higher in performance than MR-J2-Super series servo
amplifier.
Brake unit
Used when the regenerative option cannot provide enough regenerative
power.
Can be used the 5kW or more servo amplifier.
Power regenerative converter
Used when the regenerative option cannot provide enough regenerative
power.
Can be used the 5kW or more servo amplifier.
Regenerative option
Used when the built-in regenerative resistor of the servo amplifier does not
have sufficient regenerative capability for the regenerative power generated.
Alarm history clear Alarm history is cleared.
Output signal selection
(Device settings)
The pins that output the output devices, including the trouble (ALM) and the
dynamic brake interlock (MBR), can be changed to certain pins of the CN3
connectors.
Output signal (DO)
forced output
Output signal can be forced on/off independently of the servo status.
Use this function for output signal wiring check, etc.
Test operation mode
JOG operation
positioning operation DO forced output program operation.
However, MR Configurator is necessary for positioning operation.
Analog monitor output Servo status is output in terms of voltage in real time.
MR Configurator
Using a personal computer, parameter setting, test operation, status display,
etc. can be performed.

B Servo Amplifier
