MELSERVO-JN
Just turn on the one-touch tuning function to automatically complete various adjustments including estimation of load to motor inertia ratio, gain adjustment and machine resonance suppression, which maximize the servo performance.
Easy setting of electronic gear
Calculation of command pulse frequency and travel distance of the ball screw is simple since the number of command pulses per revolution of motor is set to 10000 by default. Additionally, rotation angle is controlled easily just by setting one parameter.
Reliable operation with tough drive function
● Overload tough drive function
Overload tough drive function automatically adjusts machine operation to prevent an alarm occurrence when load changes in the machine are detected, and thereby reduces time losses caused by machine stops.
● Instantaneous power failure tough drive function
When an instantaneous power failure is detected, power charged in the main circuit capacitor is supplied to keep the system running.
Low voltage alarm may occur depending on the load conditions.
● Vibration tough drive function
This function readjusts the machine resonance suppression filter automatically and prevents resonance when a machine resonance frequency is changed due to aging distortion.
Safe maintenance due to separate power supply for main and control circuits
Because both the main circuit power supply and the control circuit power supply have the respective connectors, the main circuit power supply can be turned off separately. This makes setting parameters and performing maintenance, such as checking the machine status when an error occurs, safer.
With fanless body
The maintenance performance is improved by eliminating a cooling fan from the servo amplifier. There is no need to worry about the life of the cooling fan.
Drive recorder function for quick troubleshooting
● This function automatically records data before and after the alarm occurrence.
The recorded data is available in graph form even after the power is off. This enables identifying the cause of the trouble and quickly solves the issue.
● This function automatically selects data to be recorded based on alarms. Information on the causes of alarm is read and monitored easily.
MR Configurator2 is required to display data in the drive recorder in graph form.
Various control modes
● Speed/torque control operation
The speed control mode and the torque control mode are supported. (The speed and the torque commands are set internally by parameters.)
● Torque limit
The torque generated by the servo motor can be controlled by setting parameters.
MELSERVO-JN complies with global standards.
