Special multi axis positioning controller for NSD servo system.
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 MITSUBISHI A1S68DAI PDF catalog A1S68DAI
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.
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 MITSUBISHI A1S68DAI PDF catalog. .
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points. MELSECNET/B.

Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 2 line /2 line type.
Type of input and output terminal.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module. 8 channels.
Input: DC-10 ~ 10V, DC4 ~ 20mA.
Output (resolution): -2000 ~ 2000.
Transform speed: 2.5ms/1 channel.
47 point terminal station.
Each channel D can be set A/ transform the.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
MITTSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian A1S68DAI PDF datasheet.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithhmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process A1S68DAI PDF datasheet.
