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.
Chapter 12
Gain changing function
You can switch between gains during rotation and gains during stop or use
an input device to change gains during operation.
Section 7.6
Advanced vibration
suppression control
This function suppresses vibration at the arm end or residual vibration. Section 7.4
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Section 7.2
Low-pass filter
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Section 7.5
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.
Slight vibration suppression
control
Suppresses vibration of
1 pulse produced at a servo motor stop. Parameters No.PB24
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.
Chapter 6
Brake unit
Used when the regenerative option cannot provide enough regenerative
power.
Can be used the 5kW or more servo amplifier.
Section 11.3
Return converter
Used when the regenerative option cannot provide enough regenerative
power.
Can be used the 5kW or more servo amplifier.
Section 11.4
Regenerative option
Used when the built-in regenerative resistor of the servo amplifier does not
have sufficient regenerative capability for the regenerative power generated.
Section 11.2
Alarm history clear Alarm history is cleared. Parameter No.PC21
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.
Section 4.5.1 (1) (d)
Test operation mode
JOG operation
positioning operation DO forced output.
However, MR Configurator is necessary for positioning operation.
Section 4.5
Analog monitor output Servo status is output in terms of voltage in real time. Parameter No.PC09
MR Configurator
Using a personal computer, parameter setting, test operation, status display,
etc. can be performed.
