MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 5.5KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy FX2NC-16MT Manual FX2NC-16MT PROGRAMMING MANUAL II FX2NC-16MT
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure FX2NC-16MT Manual FX2NC-16MT PROGRAMMING MANUAL II.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements. Axis of control: 1.
Applicable PLC:FX1N, FX2N, FX3U, FX2NC (to FX2NC-CNV-IF).
Applicable PLC:FX3UC (to FX2NC-CNV-IF or FX3UC-1PS-5V).
7 operating modules required for easy positioning control are provided.
Type of instruction, please refer to the list in front of you FX2NC-16MT Manual FX2NC-16MT PROGRAMMING MANUAL II.
One can control a shaft.
FX3U, PLC FX2N can connect up to 8 units,
PLC FX2NC can connect up to 4 units,
PLC FX3UC can connect up to 7 units, so that it can control more than one independent axis.
Maximum can output 100kHz pulse train.
Positioning control through the control program. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 280KW.
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.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetiic 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 mmotor FX2NC-16MT Manual FX2NC-16MT PROGRAMMING MANUAL II FX2NC-16MT Manual FX2NC-16MT PROGRAMMING MANUAL II.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
