Drive: MR-H_ACN series built-in positioning function.
Rated output: 11KW.
In servo drive speed closed loop,
Rotor speed measurement accuracy is very important to improve the dynamic and static characteristics of the speed control loop.
In order to seek the balance between measurement precision and system cost, incremental photoelectric encoder is generally used as the speed measuring sensor,
The corresponding method is M/T velocity measurement QJ71FL71-B5-F01
Although the M/T measurement method has a certain measurement accuracy and a wide range of measurement,
But this method has its inherent defects,
Mainly includes: the measurement period must be detected at least one complete encoder pulse, limiting the minimum detectable speed.
2 control system for speed control of the timer switch is difficult to maintain synchronization,
Can not guarantee the accuracy of measurement in the situation where the speed change is larger.
Therefore, it is difficult to improve the speed tracking and control performance of servo drive by using the traditional speed loop design method. Total points: 20 points.
Input points: 12 points.
Output points: 8 points.
Voltage: AC220V.
Output type: relay.
Outline dimension: 75*75*90.
MITSUBISHI FX1S series PLC is suitable for the smallest package,
It is the preferred target for low cost users to seek powerful control over a limited range of I/0.
FX1S provides up to 30 I/O points, and can be transmitted through serial communication data,
MT models also have the ability to locate, widely used in a variety of small mechanical equipment. 20 pin connector on both ends of the circular multi-core cable.
Length 3M. 2 axes.
2 axis linear interpolation.
Control unit: pulse, mm, inch, degree.
Determine the location of the number of data: 400/1 axis.
40 pin connector.
Control mode: position automatic acceleration and deceleration time: 64-4999ms pulse train output.
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.
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.
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.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process.
