MR Configurator
High-resolution encoder of 262144 pulses/rev is used as a rotary servo motor
encoder.
Merely setting a home position once makes home position return unnecessary
at every power-on.
Switches gains by using input devices or gain switching conditions (including the
servo motor speed).
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 Configurator installed personal computer and servo amplifier.
MR Configurator is necessary for this function.
Can simulate machine motions on a personal computer screen on the basis of
the machine analyzer results.
MR Configurator is necessary for this function.
Personal computer with MR Configurator changes gains automatically and
searches for overshoot-free gains in a short time.
MR Configurator is necessary for this function.
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.
Output signal can be forced on/off independently of the servo status.
Use this function for output signal wiring check, etc.
JOG operation positioning operation DO forced output
However, MR Configurator is necessary for positioning operation.
Servo status is output in terms of voltage in real time.
Using a personal computer, parameter setting, test operation, status display,
etc. can be performed.
