This realizes a high response and stable control following the ideal model. The
two-degrees-of-freedom-model model adaptive control enables you to set a
response to the command and response to the disturbance separately.
Additionally, this function can be disabled. Refer to section 7.5 for disabling this
function. This is used by servo amplifiers with software version B4 or later. Check
the software version with MR Configurator2.
This servo amplifier is used as a position control servo.
This servo amplifier is used as a speed control servo.
This servo amplifier is used as a torque control servo.
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.
Using an input device or gain switching conditions (including the servo motor
speed) switches gains.
This function suppresses vibration at the arm end or residual vibration of the
machine.
The machine resonance suppression filter 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.
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
Used when the built-in regenerative resistor of the servo amplifier does not have
sufficient regenerative capability for the regenerative power generated.
Alarm history is cleared.
The pins that output the output devices, including ALM (Malfunction) and INP (In-
position), can be assigned to certain pins of the CN3 connectors.
Output signal can be forced on/off independently of the servo status.
Use this function for output signal wiring check and others.
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is necessary for this function.
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
Linear servo system can be configured using a linear servo motor and linear
encoder.
Direct drive servo system can be configured to drive a direct drive motor.
One click on a certain button on MR Configurator2 adjusts the gains of the servo
amplifier.
MR Configurator2 is necessary for this function.
