Function list
The following table lists the functions of this servo. For details of the functions, refer to each section of the detailed explanation
field.
Function Description Detailed
explanation
Model adaptive control This realizes a high response and stable control following the ideal model. The two-degrees-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 the following for disabling this function.


Cyclic synchronous position mode
(CSP) Operation is performed in the cyclic synchronous position mode. 
Cyclic synchronous velocity mode
(CSV) Operation is performed in the cyclic synchronous velocity mode.

Cyclic synchronous torque mode
(CST) Operation is performed in the cyclic synchronous torque mode.

Touch probe When the touch probe signal is turned on, the current position is latched. This is used with servo
amplifiers with software version A1 or later.  Page 544
Touch probe
High-resolution encoder High-resolution encoder of 4194304 pulses/rev is used as the encoder of the rotary servo motor
compatible with the MELSERVO-J4 series. 
Absolute position detection system Merely setting a home position once makes home position return unnecessary at every power-on.

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.  Page 247

filter
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.

Machine analyzer function Analyzes the frequency characteristic of the mechanical system by simply connecting a 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. [Pr. PE41]
Slight vibration suppression control Suppresses vibration of

1 pulse produced at a servo motor stop. [Pr. PB24]
Auto tuning Automatically adjusts the gain to optimum value if load applied to the servo motor shaft varies.  Page 237
