1. FUNCTIONS AND CONFIGURATION

1.3 Function list

The following table lists the functions of this servo. For details of the functions, refer to the reference field.

Function

Description

Reference

Positioning by program operation

Operation is performed in accordance with the contents of any
program selected from among pre-created 16 programs.
Use the external input signal or communication function to choose
the program.

Section 4.2

Manual home position return

Dog type, count type, data setting type, stopper type, home
position ignorance, dog type rear end reference, count type front
end reference, dog cradle type

Section 4.4

Multidrop communication

Up to 32 axes of MR-J2S-CL are controllable simultaneously by
RS-422 communication.

Section 4.6.3

Chapter 15

High-resolution encoder

High-resolution encoder of 131072 pulses/rev is used as a servo
motor encoder.

Absolute position detection system

By merely setting the home position once, home position return
need not be done at each power on.

Section 4.5

Gain changing function

You can switch between gains during rotation and gains during
stop or use an external signal to change gains during operation.

Section 9.5

Adaptive vibration suppression control

Servo amplifier detects mechanical resonance and sets filter
characteristics automatically to suppress mechanical vibration.

Section 9.3

Low-pass filter

Suppresses high-frequency resonance which occurs as servo
system response is increased.

Section 9.4

Machine analyzer function

Analyzes the frequency characteristic of the mechanical system by
simply connecting a 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.

Gain search function

Personal computer changes gains automatically and searches for
overshoot-free gains in a short time.

Slight vibration suppression control

Vibration of 1 pulse at servo motor stop is suppressed.

Parameter No. 20

Electronic gear

The electronic gear is used to make adjustment so that the servo
amplifier setting matches the machine moving distance. Also,
changing the electronic gear value allows the machine to be moved
at any multiplication ratio to the moving distance using the servo
amplifier.

Section 5.2.1

Auto tuning

Automatically adjusts the gain to optimum value if load applied to
the servo motor shaft varies. Higher in performance than MR-J2
series servo amplifier.

Chapter 8

S-pattern acceleration/deceleration time
constant

Acceleration/deceleration can be made smoothly.

Section 4.2.1 (2) 2)

Section 5.2.3

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 14.1.1

Brake unit

Used when the regenerative brake option cannot provide enough
regenerative power.
Can be used with the MR-J2S-500CL MR-J2S-700CL.

Section 14.1.2

Return converter

Used when the regenerative brake option cannot provide enough
regenerative power.
Can be used with the MR-J2S-500CL MR-J2S-700CL.
