Power: 0.4kw.
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 MITSUBISHI A1SJ71QC24N1.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table A1SJ71QC24N1
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 MITSUBISHI A1SJ71QC24N1.
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. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 132KW.
Frequency converter common frequency of a given way: the operator keyboard is given, the contact signal given, analog signal given, the pulse signal given and communication methods given, etc MITSUBISHI A1SJ71QC24N1. .
These frequencies have their advantages and disadvantages, and should be selected according to the actual needs.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions. Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC5V.
Output current: 8A.
For Q4ARCPU.
The control module monitors the power supply, the error
CPU state,
And its own error state.
It sends out
Error signal a6raf and open the corresponding
Relay output.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should bee determined accoording to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A1SJ71QC24N1.
Taking into account the future adjustment and expansion,
In general should be estimaateed on the total number of points plus the amount of spare 20%~30% A1SJ71QC24N1.
The following describes the centralized control system I/O points of the estimate.
