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 automatic operation
Select the required ones from among 31 preset point tables and
perform operation in accordance with the set values.
Use the external input signal or communication function to choose
the point tables.
Section 4.2
Varied speed operation
Servo motor speed can be varied continuously until the preset
moving distance is reached. (Max. set speeds: 31 speeds)
Section 4.2.6 (2)
Automatic continuous positioning
operation
By merely choosing one point table and starting operation,
positioning can be executed continuously in accordance with
several point tables.
Section 4.2.6 (1)
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-CP 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 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.
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 5.2.3
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 14.1.1
Brake unit
Used when the regenerative option cannot provide enough
regenerative power.
Can be used with the MR-J2S-500CP MR-J2S-700CP.
Section 14.1.2
Return converter
Used when the regenerative option cannot provide enough
regenerative power.
Can be used with the MR-J2S-500CP MR-J2S-700CP.
