MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 30KW.
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 FR-A740-45K-CHT Applied Manual FR-A740-45K-CHT INSTRUCTION MANUAL.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) FR-A740-45K-CHT
If the given acceleration time is too short, the output frequency of the inverter is far more than the 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-A740-45K-CHT Applied Manual FR-A740-45K-CHT INSTRUCTION MANUAL. Auxiliary parts for FX3GC and FX3UC. "Life is 40000 hours, and the user can simply change the background light.
Application Series: F943GOT. Convert connectors to fast connectors.
According to the location of the connection equipment distribution module. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 1 FR-A740-45K-CHT Applied Manual FR-A740-45K-CHT INSTRUCTION MANUAL. 5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load. MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.75KW.
Inverter output for the PWM wave, containing more harmonic.
Frequency conversion power sensor through the input voltage and current signals to exchange sampling,
Sampling value through cable, optical fiber and other transmission systems and digital input frequency conversion power analyzer,
The samplingg value of the voltage and current is calculated by the digital input frequency conversion power analyzer,
It can obtain the parameters such as voltage effective value, current effecttive value, fundamental wave voltage, fundamental current, harmonic voltage, harmonic current, active power, fundamental wave power and harmonic power FR-A740-45K-CHT Applied Manual FR-A740-45K-CHT INSTRUCTION MANUAL FR-A740-45K-CHT Applied Manual FR-A740-45K-CHT INSTRUCTION MANUAL.
