16. INDEXER POSITIONING OPERATION
16.1.3 Function list
The following table lists the functions of this servo. For details of the functions, refer to the reference field.
Function Description Reference
Automatic operation mode 1
(Rotation direction specifying
indexer)
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.
Section 16.7.2
Automatic operation mode 2
(Shortest rotating indexer)
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.
Section 16.7.3
Manual operation mode
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.
Section 16.8
Home position return Torque limit changing dog type, torque limit changing data setting type Section 16.9
High-resolution encoder
High-resolution encoder of 262144 pulses/rev is used as a servo motor
encoder.
Absolute position detection
system
By merely setting the home position once, home position return need not be
done at each power on.
Section 16.10
Gain changing function
You can switch between gains during rotation and gains during stop or use
an input device to change gains during operation.
Section 10.6
Advanced vibration suppression
control
This function suppresses vibration at the arm end or residual vibration. Section 10.4
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Section 10.2
Low-pass filter
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Section 10.5
Machine analyzer function
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.
Machine simulation
Can simulate machine motions on a personal computer screen on the basis
of the machine analyzer results.
MR Configurator is necessary for this function.
Gain search function
Personal computer changes gains automatically and searches for
overshoot-free gains in a short time.
MR Configurator is necessary for this function.
Slight vibration suppression
control
Suppresses vibration of
1 pulse produced at a servo motor stop.
Parameters No.
PB24
Electronic gear
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.
Parameter No.
PA06, PA07
Auto tuning
Automatically adjusts the gain to optimum value if load applied to the servo
motor shaft varies.
Section 9.2
Regenerative option
Used when the built-in regenerative resistor of the servo amplifier does not
have sufficient regenerative capability for the regenerative power generated.
Section 14.2
Brake unit
Used when the regenerative option cannot provide enough regenerative
power.
Can be used with the servo amplifier of 5kW or more.
Section 14.3
Regeneration converter
Used when the regenerative option cannot provide enough regenerative
power.
Can be used with the servo amplifier of 5kW or more.
Section 14.4
Alarm history clear Alarm history is cleared.
Parameter No.
