"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
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. "
Power: 30kw.
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 FR-F740-1.5K-CHT.
Please select according to the required braking torque. "Power: 15kw.
Voltage: 400V
FR-F740-1.5K-CHT
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit MITSUBISHI FR-F740-1.5K-CHT.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy. "Applicable motor capacity: 5.5KW.
Rated current: 1.2A.
Power supply voltage: three phase 400V.
Frequency converter and GOT supporting the use, to achieve a higher price MITSUBISHI FR-F740-1.5K-CHT.
SIMPLE GOT series can be directly connected to the IS70 series inverter.
GOT can be directly connected with the inverter. After connecting the two, the communication parameters can be automatically set.
In addition, the software can display the soft component of the control function in the GOT, even when the multi frequency converter is connected,
Can also be unified management with 1 GOT.
Through the GOT screen to create software to import the picture data after the GOT,
Only use RS-422 connection GOT and frequency converter,
Can change the inverter speed / direction, monitoring the output frequency / output current and set a variety of parameters. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 90KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load cchanges are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) FR-F740-1.5K-CHT.
If the given acceleration time is too short, the output frequency of the inverter is far more than thhe change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall FR-F740-1.5K-CHT.
