MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
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%) F1-40MR-UL INSTRUCTION MANUAL F1-40MR-UL
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 F1-40MR-UL INSTRUCTION MANUAL. Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.Function: input / output module (internal service power supply).
Input / output points: 32 points
Input points: 16 points F1-40MR-UL INSTRUCTION MANUAL.
Output points: 16 points.
DC5V internal consumption current: 965mA.
DC24V internal consumption current: 250mA.
Input / output mode: DC input (drain / source) / transistor (drain).
In order to extend the input output of the device MITSUBISHI F1-40MR-UL Manual.
Also has a built-in power supply products.
The maximum number of points for the input and output is 256.
Expansion module: up to 16 units (in addition to the power expansion module)
The total number of CC-Link, AnyWireASLINK, and Bitty series of remote I/O is 512 points MITSUBISHI F1-40MR-UL Manual. Power: 355kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current MITSUBISHI F1-40MR-UL Manual.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 45KW.
Frequency converter common frequency of a given way: the operator keyboard is given, the contact signal given, analog signal given, the pulse signal given and communication methods given, etc..
These frequencies have their advantages and disadvantages, and should be selected according to the actual needds F1-40MR-UL Sink input type.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequeency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions F1-40MR-UL INSTRUCTION MANUAL.
