In this operation mode, the servo motor rotates in the specified direction and
performs a positioning operation to the next station divided in 2 to 255.
In this operation mode, the servo motor rotates in the shortest direction and
performs a positioning operation to the next station divided in 2 to 255.
1. Indexer JOG operation
When stopping, this JOG operation enables the servo motor to perform
positioning to the station where the servo motor can decelerate to stop.
2. JOG operation
When stopping, this JOG operation enables the servo motor to decelerate
to stop regardless of stations.
Torque limit changing dog type, torque limit changing data setting type
High-resolution encoder of 262144 pulses/rev is used as a servo motor
encoder.
By merely setting the home position once, home position return need not be
done at each power on.
You can switch between gains during rotation and gains during stop or use
an input device 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 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 a 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 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.
The electronic gear is used to make adjustment so that the servo amplifier
setting matches the machine moving distance. Also, changing the electronic
gear value allows the machine to be moved at any multiplication ratio to the
moving distance using the servo amplifier.
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.
Used when the regenerative option cannot provide enough regenerative
power.
Can be used with the servo amplifier of 5kW or more.
Used when the regenerative option cannot provide enough regenerative
power.
Can be used with the servo amplifier of 5kW or more.
Alarm history is cleared.
