1. FUNCTIONS AND CONFIGURATION
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
Positioning by automatic operation
Select the required ones from among 31 preset point tables and perform
operation in accordance with the set values.
Use the external input signal or communication function to choose the point
tables.
Section 4.5
Varied speed operation
Servo motor speed can be varied continuously until the preset moving
distance is reached. (Max. set speeds: 255 speeds)
Section 4.5.2
(2)(c)
Automatic continuous positioning
operation
By merely choosing one point table and starting operation, positioning can
be executed continuously in accordance with several point tables.
Section 4.5.2
(2)(c)
Home position return
Dog type, count type, data setting type, stopper type, home position
ignorance, dog type rear end reference, count type front end reference, dog
cradle type
Section 4.7
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 4.9
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 9.6
Advanced vibration suppression
control
This function suppresses vibration at the arm end or residual vibration.
Section 9.4
Adaptive filter
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Section 9.2
Low-pass filter
Suppresses high-frequency resonance which occurs as servo system
response is increased.
Section 9.5
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 8.2
S-pattern
acceleration/deceleration time
constant
Acceleration/deceleration can be made smoothly.
Parameters No.
PC13
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 13.2
Brake unit
Used when the regenerative option cannot provide enough regenerative
power.
Can be used with the servo amplifier of 5kW or more.
