Setting a home position once makes home position return unnecessary at every
power-on.
This function achieves a high response and stable control following the ideal model.
The two-degrees-of-freedom model adaptive control enables you to set a response
to the command and a response to the disturbance separately.
Additionally, this function can be disabled. To disable this function, refer to section
7.4 of "MR-JE-C_ Servo Amplifier Instruction Manual".
Positioning is performed based on the specified travel distance from a status display
"0" of current/command positions at start.
This function is available with servo amplifiers with software version A4 or later.
The touch probe function is available in the profile mode or the positioning mode.
When the touch probe 1 signal turns on, the current position is latched. The latched
data can be read with communication commands.
The touch probe function is available in the profile mode or the positioning mode.
When the touch probe 1 signal turns on, this function converts the remaining
distance to the travel distance set in [Pr. PT30 Touch probe sensor - Travel distance
before stop (lower four digits)] and [Pr. PT31 Touch probe sensor - Travel distance
before stop (upper four digits)].
This function is available with servo amplifiers with software version A4 or later.
When the unit of position data of the profile mode is set to degree, the detection of
[AL. E3.1 Multi-revolution counter travel distance excess warning] is disabled and
the home position is retained even if the servo motor rotates 32768 revolutions or
more in the same direction. Thus, the current position is restored after the power is
cycled.
This function can be used with the absolute position detection system.
Command pulse train form can be selected from among three different types.
High-resolution encoder of 131072 pulses/rev is used for the encoder of the servo
motor compatible with the MELSERVO-JE series.
You can switch gains during rotation and during stop, and can use an
input device to switch gains during operation.
This function suppresses vibration or residual vibration at an arm end.
This filter function (notch filter) decreases the gain of the specific frequency to
suppress the resonance of the mechanical system.
When a load is mounted to the servo motor shaft, resonance by shaft torsion during
driving may generate a mechanical vibration of high frequency. The shaft resonance
suppression filter suppresses the vibration.
The servo amplifier detects mechanical resonance and sets filter characteristics
automatically to suppress mechanical vibration.
Suppresses high-frequency resonance which occurs as the servo system response is
increased.
Analyzes the frequency characteristic of the mechanical system by simply
connecting an MR Configurator2 installed personal computer and the servo
amplifier.
MR Configurator2 is necessary for this function.
