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.
Servo motor speed can be varied continuously until the preset
moving distance is reached. (Max. set speeds: 31 speeds)
By merely choosing one point table and starting operation,
positioning can be executed continuously in accordance with
several point tables.
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
High-resolution encoder of 131072 pulses/rev is used as a servo
motor encoder.
By merely setting the home position once, home position return
need not be done at each power on.
You can switch between gains during rotation and gains during
stop or use an external signal to change gains during operation.
Servo amplifier detects mechanical resonance and sets filter
characteristics automatically to suppress mechanical vibration.
Suppresses high-frequency resonance which occurs as servo
system response is increased.
Analyzes the frequency characteristic of the mechanical system by
simply connecting a servo configuration software-installed
personal computer and servo amplifier.
Can simulate machine motions on a personal computer screen on
the basis of the machine analyzer results.
Personal computer changes gains automatically and searches for
overshoot-free gains in a short time.
Vibration of 1 pulse at servo motor stop is suppressed.
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.
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.
Acceleration/deceleration can be made smoothly.
Used when the built-in regenerative brake resistor of the servo
amplifier does not have sufficient regenerative capability for the
regenerative power generated.
Used when the regenerative brake option cannot provide enough
regenerative power.
Can be used with the servo amplifier of 5kW or more.
Used when the regenerative brake option cannot provide enough
regenerative power.
Can be used with the servo amplifier of 5kW or more.
