MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 500KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FX3U-48MT/DSS Basic & Applied Instructions Edition Manual FX3U-48MT/DSS PROGRAMMING MANUAL FX3U-48MT/DSS
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor FX3U-48MT/DSS Basic & Applied Instructions Edition Manual FX3U-48MT/DSS PROGRAMMING MANUAL.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Function extension board for RS-422 communication.
No DC24V consumption, no occupancy of the input output (FX1S and FX1N of the host computer). Input / output type: transistor output (source).
Output points: 8 points.
Input and output points: 8 points FX3U-48MT/DSS Basic & Applied Instructions Edition Manual FX3U-48MT/DSS PROGRAMMING MANUAL.
Because all models of FX series are built in high speed counter,
So the high speed control can be realized by the simple procedure.
The input of the basic unit is built in the anti jitter filter,
One part as digital filter,
Sensitivity adjustment unit can reach 1ms.
Using high speed counter automatically adjusted to the minimum value.
Through the high cost of the built-in positioning function and the expansion function to increase the number of control axis.
Extended function expansion board and special adapter,
Data links and communication with external serial devices.
FX2N extension module.
The expansion module is an input and output expansion device of the power supply from the basic unit or the expansion unit,
Can chooose the relay or crystal output models, to 8 points for the unit to connect FX3U-48MT/DSS Basic & Applied Instructions Edition Manual FX3U-48MT/DSS PROGRAMMING MANUAL.
Can be extended to FX3GA/FX3G, FX3GE, FX3GC, as well as FX3U, FX3UC series,
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-1PS-5V FX3U-48MT/DSS Basic & Applied Instructions Edition Manual FX3U-48MT/DSS PROGRAMMING MANUAL.
The number of connection points depends on the basic unit and the expansion unit.
