Transmission line unit for MELSECNET/MINI (-S3) twisted pair data link.
Loop: twisted pair I/F.
Remote station: twisted pair line I/F.
MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations.
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system Q173J2B2CBL1M
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc..
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 75KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection).
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall. MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 11.0kw.
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 0.888ms.
Such systems will be able to provide high reliability and high performance.
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.
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.
