MITSUBISHI MR-J4-500B4

Power: 5.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor .
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table MR-J4-500B4
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used. But please pay attention to the allowable brake use rate MR-J4-500B4.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor .
The installation of thermal relay, to avoid overheating and burn the braking resistor. Output points: 32 points
Output form: Transistor (drain type).
Connection status: connector.
In order to extend the input output of the device.
Also has a built-in power supply products MR-J4-500B4.
The maximum number of points for the input and output is 256 .
Expansion module: up to 16 units (in addition to the power expansion module)
The total number of CC-Link, AnyWireASLINK, and Bitty series of remote I/O is 512 points. Motor series: ultra low inertia, low power.
Rated output power: 0.1kw.
Rated speed: 3000r/min.
Whether to take the brake: No.
Axis end: D type shaft.
Protection level: IP55 does not include the shaft part and the connector.
Features: ultra low inertia is suitable for high frequency operation.
Application examples: the insertion device, the assembly machine. Input and output points: 512 points.
Input / output data points: 8192 points.
Program capacity: 28k.
Basic command processing speed (LD command) S:0.2.
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 time is accounted for the vast majority of.
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 cappacity: it is a measure of how much the user application can store the number of indicators MR-J4-500B4.
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 lloggical operation instructions each account for 1 words MR-J4-500B4. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
