40 pin connector.
Support high resolution devices. Pulse input and high speed counter module product group satisfying high speed and high precision control application.
High speed counter module for counting high-speed pulse train Q26UDEHCPU
Can be used in combination with the external encoder for positioning and other control.
The maximum count rate can be switched, and the low frequency pulse is counted from the high speed pulse to the rising edge / falling edge Q26UDEHCPU PDF.
Each 1 channel is equipped with 2 points of external uniform output.
Can be selected according to the use of "consistent output function", "continuous comparison function", to achieve high-speed control of external equipment. (QD64D2)
Provides a variety of functions, such as the same output test function (using a continuous comparison function), the default function, the latch counter function,
In order to meet the needs of various applications Q26UDEHCPU PDF. (QD64D2)
The maximum count rate of the input pulse can be up to 8Mpps (differential input, 2 phase, 4 double frequency) MITSUBISHI Programming Manual.
Can be in the semiconductor, liquid crystal manufacturing and other high position accuracy requirements of the equipment,
Perform accurate position tracking using high resolution encoders. (QD65PD2)Input and output points: 2048 points.
Input / output data points: 8192 points MITSUBISHI Programming Manual.
Program capacity: 92k.
Basic command processing speed (LD command) S:0.15.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution timee is accounted for the vast majority of MITSUBISHI Programming Manual Q26UDEHCPU Manual .
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
Light emitting diode two: the input of a photo coupler and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal.
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.
Photoelectric three levels: in the light of the light signal conduction, the degree of light signal and the intensity of the light signal.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler.
User program storage capacity: it is a meaasure of how much the user application can store the number of indicators Q26UDEHCPU Programming Manual.
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 llogical operation instructions each account for 1 words Q26UDEHCPU Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
