SEMI-F47 function
This realizes a high response and stable control following the ideal model. The
two-degree-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 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 262144 pluses/rev is used for the encoder of the rotary
servo motor compatible with the MR-J4W2-0303B6 servo amplifier.
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.
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 generated at a servo motor stop.
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
This is not available with MR-J4W2-0303B6 servo amplifier.
Alarm history is cleared.
The output devices including ALM (Malfunction) and INP (In-position) can be
assigned to specified pins of the CN3 connector.
Output signal can be forced on/off independently of the servo status.
Use this function for checking output signal wiring, etc.
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is necessary for this function.
Servo status is outputted in terms of voltage in real time.
Using a personal computer, you can perform the parameter setting, test operation,
monitoring, and others.
This is not available with MR-J4W2-0303B6 servo amplifier.
This is not available with MR-J4W2-0303B6 servo amplifier.
One click on a certain button on MR Configurator2 adjusts the gains of the servo
amplifier.
MR Configurator2 is necessary for this function.
This is not available with MR-J4W2-0303B6 servo amplifier.
