Positioning mode
(Point table method) Select the predefined 255 point tables, and operate them according to the setting values.
Use external input signals or communication functions to select point tables.
○ ×
Positioning mode
(Program method) Select one from the predefined 256 programs, and operate it according to the program
content. Use external input signals or communication functions to select programs.
× ○
Roll feed display function
Set the status display of commanded position and current position at the start to "0", and
perform positioning for the defined travel distance.
○ ○
Mark detection function
(Current position latch
function)
Mark detection signal is turned on, the current position is latched.
Latched data can be read using a communication command.
○ ○
Manual home position return
Dog type, count type, data set type, stopper type, home position ignorance, dog type rear
end reference, count type front end reference, dog cradle type, dog type last Z-phase
reference, Dogless Z-phase reference
○ ○
High-resolution encoder
A high-resolution encoder capable of 4194304 pulses/rev is used as the encoder for the
rotary servo motor compatible with the MELSERVO-J4 series.
○ ○
Absolute position detection
system By setting the home position once, it will be unnecessary to return to the home position
each time the power is turned on.
○ ○
Gain Switching Function
Gain can be switched during rotation and when stopped, and also when using the input
device during the operation.
○ ○
Advanced vibration
suppression control II
This function controls residual vibration or vibration at the end of the arm. ○ ○
Shaft resonance
suppression filter
When a load is put on the servo motor shaft, a high-frequency machine vibration may be
generated due to resonance caused by shaft torsion while the servo motor is being driven.
The shaft resonance suppression filter is the filter that controls this vibration.
○ ○
Adaptive filter II
With this function, the servo amplifier detects machine resonance and sets filter properties
automatically, and then controls the vibration of the machine system.
○ ○
Low-pass filter
When a servo system response is raised, it suppresses the high-frequency resonance
generated.
○ ○
Machine analyzer function
The frequency properties of the machine system are analyzed by only connecting the
servo amplifier and the personal computer where MR Configurator2 is installed.
MR Configurator2 is necessary for this function.
○ ○
Robust filter
If it is not possible to raise the response because the load to motor inertia ratio is high due
to the roll feed shaft, etc., the disturbance response can be improved.
○ ○
Slight Vibration Suppression
Control
A vibration of ±1 pulse is suppressed when the servo motor stops.
○ ○
Electronic gear Position command can be set to 1/864-33935 times. ○ ○
Auto Tuning
Automatically adjusts the optimum servo gain even if the load applied on the servo motor
shaft changes.
○ ○
Brake unit
Used when there is insufficient regenerative ability in the regenerative option.
5 kW or higher servo amplifier can be used.
○ ○
Power regeneration
converter Used when there is insufficient regenerative ability in the regenerative option.
5 kW or higher servo amplifier can be used.
○ ○
Regenerative options
Used when the generated regenerative power is high and there is insufficient regenerative
ability in the internal regenerative resistor of servo amplifier.
○ ○
Alarm History Clear Deletes the alarm history. ○ ○
Input signal selection
(device settings) Input devices such as ST1 (forward rotation start), ST2 (reverse rotation start), and SON
(servo-on) can be assigned to a specific CN1 connector pin.
○ ○
Output signal selection
(device settings) Output devices such as MBR (electromagnetic brake interlock) can be assigned to a
specific CN1 connector pin.
○ ○
Output signal (DO) forced
output Output signals can be turned on/off forcibly regardless of the status of the servo.
Use for output signal wiring checks, etc.
○ ○
Command pulse selection Phase A/phase B pulse train
○ ○
Torque limit The servo motor torque can be limited. ○ ○
Status display The servo status is displayed on the 5-digit, 7-segment LED indicator. ○ ○
