"MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 0.2kw.
SSCNET interface.
Voltage: 3 phase AC200VAC or single phase AC230V.
Complete synchronization system with SSCNET high speed serial communication,
The communication cycle between the controller and the servo amplifier is the longest 0 MELDAS 60/60S series . 888ms.
Such systems will be able to provide high reliability and high performance MELDAS 60/60S series
When connecting the servo system with SSCNET,
In the motion system, the parameters of the servo amplifier and the acquisition of the data will be displayed on the motion controller.
Connect a dedicated cable with an amplifier and a controller to form a SSCNET system.
This simple connection method reduces the routing time and helps to prevent noise MELDAS 60/60S series .
Even in the MELSERVO-J2-SUPER series products using high resolution coding standards, the command frequency is no limit.
It is only necessary to add a battery on the servo amplifier, which can form the absolute value system.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use. "Drive unit.
MITSUBISHI universal AC servo amplifier MELSERVO-J4 series MELDAS 60/60S series .

Interface: SSCNET III /H.
Power supply: three phase AC400V.
Special specifications: full closed control 4 wire / support mechanical end encoder ABZ phase input / support positioning mode.
Support position control, speed control, torque control.
Position control to follow the position instructions.
When the control is inserted, the position control is performed.
Speed control follows the speed command to control the speed within a certain range.
Torque control to follow the torque command to control the stable torque.
Function of switching amplitude. The increase in the process of switching and stopping,
And in the operation of the use of the switching signal, switching growth. Drive: MR-H_ACN series built-in positioning function.
Rated output: 0.6KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement.
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum deetectable speed MELDAS 60/60S series DDB Interface Manual.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is largger MELDAS 60/60S series DDB Interface Manual.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method.
