Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 630KW.
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-ABR-H1 FR-ABR-H1.5K5K Manual FR-ABR-H1.5K Instruction manual.
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-ABR-H1.5K Manual FR-ABR-H1.5K Instruction manual.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Output points: 32 points.
Output form: transistor.
Connected programmable logic controller: FX1NC, FX2NC, FX3UC.
Weight: 0.2KG.
FX2NC expansion module can be directly connected to the FX1NC, FX2NC, PLC FX3UC on the expansion of the input and output FR-ABR-H1.5K Manual FR-ABR-H1.5K Instruction manual.
Do not need to connect the cable and so on, therefore can carry on the compact expansion. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 1.5KW.
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 impaact on the mechanical and electrical FR-ABR-H1.5K Manual FR-ABR-H1.5K Instruction manual.
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 FR-ABR-H1.5K Manual FR-ABR-H1.5K Instruction manual.
