FR-F720-3.7K Manual MITSUBISHI INVERTER FR-F720-3.7K BASIC Instruction manual

Power: 220kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
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 MITSUBISHI INVERTER Instruction manual.
Please select according to the required braking torque. MITSUBISHI inverter FR-A740 series FR-F720-3.7K
Voltage level: 3 phase 400V.
Frequency converter capacity: 11KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
High level driving performance MITSUBISHI INVERTER Instruction manual.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder.
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc MITSUBISHI INVERTER Instruction manual. ) and torque control. Power: 7.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed FR-F720-3.7K Instruction manual. Does not remove the short circuit chip will lead to overheating of the brake resistor FR-F720-3.7K Instruction manual.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-F720-3.7K Instruction manual.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor.
Thee installation of thermal relay, to avoid overheating and burn the braking resistor FR-F720-3.7K Manual . Analog input expansion board (2 channel).Power: 30kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.999 and above (100% load) MITSUBISHI INVERTER Instruction manual.
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function.
