Multi axis positioning controller.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 points.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor A1SJ71LP21 PDF.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal A1SJ71LP21
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc A1SJ71LP21 PDF. .
In general, a reversible DC drive systemm controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points A1SJ71LP21 PDF A1SJ71LP21 Manual . Analog channel: 4 channels.
Input / output (resolution): 0 ~ 4000.
Conversion speed: 100ms/4 channel.
Analog module installation.
Power supply: DC24V.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system MITSUBISHI Reference Manual .
MITSUBISHI PLC detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add MITSUBISHI Reference Manual .
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong MITSUUBISHI Reference Manual A1SJ71LP21 Reference Manual .
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy too guarantee the timeliness A1SJ71LP21 Manual .
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
