MITSUBISHI A1SX71 Market price | A1SX71 Introduction

Connecting cable for handheld GOT and PLC.
Cable length: 1.5 meters.
Application: RS-422 connection (FX series). Memory format: EEPROM.
Number of steps: up to 2000 steps can be used.
Battery support: do not.
Method for writing and deleting: the device is installed on the PLC, and is written and deleted by the peripheral device.
Note: the built-in program transfer function (FX1S and FX1N host generic) A1SX71 MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 1.5KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation. To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitted.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve. Series Name: A953GOT.
Size: 6 inches.
Resolution: 320 * 240.
Display device: STN color display.
Display color: 8 color.
Power supply: DC24V.
The built-in RS-232 communication interface.
Memory card: 1M.
Design any machine interface, generally have to consider the system response time, user assistance mechanism, error information processing and command mode four aspects.
System response time is too long to be the most users in the interactive system,
In addition to the absolute length of the response time, the user is also very concerned about the difference in response to different commands in response time,
If too wide users will be difficult to accept; user assistance mechanism should be integrated,
Avoid overlay systems that cause users to turn to a guide and have to browse a large number of irrelevant information;
Error and warning information must be selected in terms of user''s clarity and meaning,
At the same time, it should be as far as possible to provide some suggestions on the recovery of errors.
In addition, when the error message is displayed, the effect is better if it is supplemented by the auditory (Bell) and visual (special color) stimulus;
Command mode is the best menu and keyboard commands, for the user to choose.
