"MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.4KW.
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 device is the first 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, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "
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 FR-E720S-0
FR-E720S-0.4K4K.
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 FR-E720S-0.4K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Voltage level: three phase 400V.
Applicable motor capacity: 315kw.
Substrate coating: have.
Built in DC reactor.
The operating frequency of the fixed alternating current is converted to DC power. Power: 15kw.
Voltage: 400V.
Purpose: high frequency braking resistor FR-E720S-0.4K.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 0.4kw.
SLD converter rated current: 4.6A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Compatibility with existing models.
Transducer installation size and FR-F700 (P) series of the same, so you do not need to worry about the replacement operation.
(rectifier sepparation type will vary)
Also, but also through the use of options (FR-A8TAT), FR-F700 (P) series installed control loop terminal station FR-E720S-0.4K.
Built in 2 PID arithmetic. In the inverter can be PID control of the motor state at the same timme, used in the control of the external machine FR-E720S-0.4K.
No external PID controller is used to control the external machine, so the system cost can be reduced.
