This servo is used as a position control servo.
This servo is used as a speed control servo.
This servo is used as a torque control servo.
Using an input device, control can be switched between position control and speed
control.
Using an input device, control can be switched between speed control and torque
control.
Using an input device, control can be switched between torque control and position
control.
High-resolution encoder of 4194304 pulses/rev is used as the encoder of the rotary
servo motor compatible with the MELSERVO-J4 series.
Merely setting a home position once makes home position return unnecessary at
every power-on.
You can switch gains during rotation and during stop, and can use an input device to
switch gains during operation.
This function suppresses vibration at the arm end or residual vibration.
This is a filter function (notch filter) which decreases the gain of the specific frequency
to suppress the resonance of the mechanical system.
When a load is mounted to the servo motor shaft, resonance by shaft torsion during
driving may generate a mechanical vibration at high frequency. The shaft resonance
suppression filter suppresses the vibration.
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
an MR Configurator2 installed personal computer and servo amplifier.
MR Configurator2 is necessary for this function.
This function provides better disturbance response in case low response level that
load to motor inertia ratio is high for such as roll send axes.
Suppresses vibration of ±1 pulse produced at a servo motor stop.
Input pulses can be multiplied by 1/10 to 4000.
Speed can be increased and decreased smoothly.
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
Used when the regenerative option cannot provide enough regenerative power.
Can be used for the 5 kW or more servo amplifier.
Used when the regenerative option cannot provide enough regenerative power.
Can be used for the 5 kW or more servo amplifier.
Used when the built-in regenerative resistor of the servo amplifier does not have
sufficient regenerative capability for the large regenerative power generated.
Alarm history is cleared.
ST1 (Forward rotation start), ST2 (Reverse rotation start), and SON (Servo-on) and
other input device can be assigned to any pins.
