1. FUNCTIONS AND CONFIGURATION
1.4 Function listThe 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-re solution encoder of 131072 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 13
Adaptive vibration
suppression control Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration. Sec tion 7.3
Low-pass filter Suppresses high-frequency resonance which occurs as servo system response is
increased. Section 7.4
Machine analyzer function Analyzes the frequency characteristic of the mechanical system by simply
connecting a MR Configurator (servo configuration software)-installed personal
computer and servo amplifier.
Machine simulation Can simulate machine motions on a personal computer screen on the basis of
the machine analyzer results. The MR Configurator (servo configuration
software) is required.
Gain search function Personal computer changes gains automatically and searches for overshoot-
free gains in a short time. The MR Configurator (servo configuration software)
is required.
Slight vibration suppression
control Suppresses vibration of 1 pulse produced at a servo motor stop. Parameter No.24
Auto tuning Automatically adjusts the gain to optimum value if load applied to the servo
motor shaft varies. Higher in performance than MELSERVO-J2 series servo
amplifier. Chapter 6
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 12.1.1
Brake unit Used when the regenerative brake option cannot provide enough regenerative
power.
Can be used with the MR-J2S-500B to MR-J2S-22KB. Section 12.1.2
Return converter Used when the regenerative brake option cannot provide enough regenerative
power.
Can be used with the MR-J2S-500B to MR-J2S-22KB. Section 12.1.3
Torque limit Servo motor torque can be limited to any value. Parameters
No.10, 11
Forced stop signal automatic
ON Forced stop (EM1) can be automatically switched on internally to invalidate it. Parameter No.23
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 4.4
(1) (e)
Test operation mode JOG operation positioning operati on motor-less operation DO forced output Section 4.4
Analog monitor output Servo status is output in terms of voltage in real time. Parame ter No. 22
MR Configurator
(Servo configuration software) Using a personal computer, parameter setting, test operation, status display,
etc. can be performed. Section 12.1.8
