Status of connected devices by means of alarm monitoring Q00JCPU-S8-SET.
Alarm output function
Process alarm.
When the digital value is in the range of preset, the output alarm Q00JCPU-S8-SET
Change rate alarm.
The output value of the output value of the digital output is too large (greater than the rate of change of the alarm limit) or too small (less than the rate of change), the output alarm Q00JCPU-S8-SET.
Achieve stability measurement
Inter channel isolation
Isolation between the channels, can prevent the connection of sensors in the channel between the cross talk, so as to achieve stable measurement .
High speed, smooth continuous analog output.
Waveform output function
Equipped with the industry''s first waveform output function.
The pre prepared waveform data can be imported into the analog output module, and the function of the analog output is simulated according to the set conversion period Q00JCPU-S8-SET.
It is not affected by the sequential scan time, and it can realize the high speed and smooth analog output. "MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 11KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
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.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency,
The equipment to the power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, which is mainly useed in the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply MITSUBISHI Q00JCPU-S8-SET.
The general inverter is 1520 times inverter price.
The main device caalled "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter MITSUBISHI Q00JCPU-S8-SET. "
