Description
This servo is used as position control servo.
This servo is used as speed control servo.
This servo is used as torque control servo.
Using external input signal, control can be switched between
position control and speed control.
Using external input signal, control can be switched between
speed control and torque control.
Using external input signal, control can be switched between
torque control and position control.
High-resolution encoder of 262144 pulses/rev is used as a
servo motor encoder.
Merely setting a home position once makes home position
return unnecessary at every power-on.
You can switch between gains during rotation and gains
during stop or use an external signal to change gains during
operation.
This function suppresses vibration at the arm end or residual
vibration.
Servo amplifier detects mechanical resonance and sets filter
characteristics automatically
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.
MR Configurator MRZJW3-SETUP221E is necessary for this
function.
Can simulate machine motions on a personal computer
screen on the basis of the machine analyzer results.
MR Configurator MRZJW3-SETUP221E is necessary for this
function.
Personal computer changes
searches for overshoot-free gains in a short time.
MR Configurator MRZJW3-SETUP221E is necessary for this
function.
Suppresses vibration of 1 pulse produced at a servo motor
stop.
Input pulses can be multiplied by 1/50 to 50.
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.
Speed can be increased smoothly in response to input pulse.
Speed can be increased and decreased smoothly.
Used when the built-in regenerative resistor of the servo
amplifier does not have sufficient regenerative capability for
the regenerative power generated.
