Input and output points: 2048 points.
Input / output data points: 8192 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure MR-J3-22KB
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
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. Type: HC-PQ type.
Output power: 0.03kw.
Rated speed: 3000r/min.
Electromagnetic brake: there.
Key axis: D type shaft.
Motor aspects: the material, structure and processing technology of the servo motor is much higher than that of AC motor,
That is when the driver output current, voltage, frequency change is fast power supply,
The servo motor can change according to the change of the response of the power supply,
Response characteristics and anti overload capacity is much higher than the AC motor drive,
Motor aspects of the serious differences between the two are fundamentally different performance.
That is not the inverter output can not change so fast power signal,
But the motor itself can not react,
So in the frequency of the internal algorithm set to protect the motor to do the corresponding overload.
Of course, even without the ability to set the output of the inverter is limited,
Some of the excellent performance of the inverter can be directly driven servo motor.
