Applicable model: A975/970/960GOT (-B).MITSUBISHI motor universal AC servo amplifier MELSERVO-J3 series.
Rated output: 22.0kw.
Interface type: SSCNET type III fiber communication.
Power specification: three phase AC200V.
High speed serial communication between the SSCNET and the servo amplifier by using the fastest up to 0.44ms communication cycle,
A fully synchronous control system can be constructed A78B
It is only necessary to insert the special optical fiber into the joint to form SSCNET III network, which greatly reduces the wiring work and reduces the possibility of false wiring.
Due to the adoption of the optical fiber communication, the anti noise ability can be greatly improved and the long distance wiring of 50 meters (maximum 800 meters x 16 axes) can be realized.
A servo amplifier to meet the full closed loop control function MR-J3-B-RJ006.
Suitable for mechanical servo optimization and adjustment!
More advanced optimization adjustment function and control function to maximize mechanical properties. "2 axes, SSCNET III type.
2 axis linear interpolation.
2 axis arc interpolation.
Control unit: mm, inch, degree, pulse.
Location data: 600 data / axis.
40 pin connector.
Through the SSCNET III cable connection to save wiring, the distance between the station up to 50m.
Absolute position system for determining the origin position is supported by the return data set operation.
In addition, the limit switch of the upper limit, the lower limit switch and the near point block signal input can be directly connected to the servo amplifier,
Thus greatly reducing the wiring requirements.
Easy to achieve high speed, high precision positioning control.
Support for multiple types of positioning control,
Including 2 ~ 4 axis 2 axis linear interpolation, circular interpolation, speed control and speed / position control, path switching control, constant speed control etc..
In addition, can use the "Configurator-QP GX" and other software,
Easy to set, monitor and debug. "Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Optical data communication line function (GI cable).
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
