1.5 Function list
The following table lists the functions of this servo. For details of the functions, refer to each section
indicated in the detailed explanation field.
Function Description
Detailed
explanation
Model adaptive control
This function achieves 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 7.4 for disabling this
function. Used by servo amplifiers with software version B4 or later. Check the
software version using MR Configurator2.
Position control mode
This servo is used as a position control servo.
Section 3.2.1
Section 3.6.1
Section 4.2
Speed control mode
This servo is used as a speed control servo.
Section 3.2.2
Section 3.6.2
Section 4.3
Torque control mode
This servo is used as a torque control servo.
Section 3.2.3
Section 3.6.3
Section 4.4
Position/speed control switch
mode
Using an input device, control can be switched between position control and speed
control.
Section 3.6.4
Speed/torque control switch
mode
Using an input device, control can be switched between speed control and torque
control.
Section 3.6.5
Torque/position control switch
mode
Using an input device, control can be switched between torque control and position
control.
Section 3.6.6
Positioning mode
In this mode, MR-JE-_A servo amplifiers are used in with point table or program
method. For details, refer to "MR-JE-_A Servo Amplifier Instruction Manual
(Positioning Mode)." The positioning mode is available with servo amplifiers with
software version B7 or later.

High-resolution encoder
High-resolution encoder of 131072 pulses/rev is used for the encoder of the servo
motor compatible with the MELSERVO-JE series.
Gain switching function
You can switch gains during rotation and during stop, and can use an input device to
switch gains during operation.
Section 7.2
Advanced vibration
suppression control II
This function suppresses vibration at the arm end or residual vibration.
Section 7.1.5
Machine resonance
suppression filter
This is a filter function (notch filter) which decreases the gain of the specific frequency
to suppress the resonance of the mechanical system.
Section 7.1.1
Shaft resonance suppression
filter
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.
Section 7.1.3
Adaptive filter II
Servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Section 7.1.2
Low-pass filter
Suppresses high-frequency resonance which occurs as servo system response is
increased.
Section 7.1.4
Machine analyzer function
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.
Robust filter
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.

Slight vibration suppression
control
Suppresses vibration of ±1 pulse produced at a servo motor stop.
[Pr. PB24]
Electronic gear
Input pulses can be multiplied by 1/10 to 4000.
[Pr. PA06]
[Pr. PA07]
S-pattern
acceleration/deceleration time
constant
Speed can be increased and decreased smoothly.
[Pr. PC03]
Auto tuning
Automatically adjusts the gain to optimum value if load applied to the servo motor
shaft varies.
Section 6.3
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 11.2
Alarm history clear
Alarm history is cleared.
[Pr. PC18]
Output signal selection
(device settings)
ST1 (Forward rotation start), ST2 (Reverse rotation start), and SON (Servo-on) and
other input device can be assigned to any pins.
