Motor series: low inertia, medium capacity.
Using a serial absolute / incremental encoder.
Rated output power: 1.5kw.
Rated speed: 3000rpm.
With a brake band.
Shaft end: straight shaft.
Performance comparison of servo motor and stepping motor.
Stepper motor as an open-loop control system, and modern digital control technology has the essential link.
In the current domestic digital control system, stepping motor is widely used A1S64AD
With the emergence of digital AC servo system, AC servo motor is more and more used in digital control system.
In order to adapt to the development trend of digital control, most of the motion control system adopts stepping motor or full digital AC servo motor as executive motor.
Although they are similar in control mode (pulse train and directional signal), there are great differences in performance and application.
The use performance of the two are compared. Output points: 64 points.
Output form: Transistor (drain type) output.
Rated open and close voltage, current: -.
Rated load voltage: DC12 ~ 24V.
Max load current: 0.2A/ point.
Response time: 1ms.
Common way: 32 point / public end.
Protection function (overload, overheat).
External wiring connection: 40 pin connector two.
Output module with mechanical relay contact mechanism,
Including the load voltage range of the relay and can be used for the output of the DC12~24V load transistor output type.
According to the load voltage, the output points of different, choose the most suitable user needs of the module.
Preventive maintenance based on the life of relay contact.
Relay output module can accumulate the number of ON of each output point.
Through the understanding of the relay contacts of the number of times, according to the relay life of preventive maintenance. Output points: 24 points.
Voltage: DC24V/AC240V, 2A/1 point, 4A/ public end.
OFF leakage current: 0mA.
Output type: relay output.
Response time: 12ms.
8 points / a common end.
50 point terminal station.
CE certification.
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.
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.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
