File language: English
MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
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%) FR-A740-75K-CHT PDF FR-A740-75K-CHT
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) FR-A740-75K-CHT PDF.
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. Power: 0 FR-A740-75K-CHT PDF. 75kw.
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. Does not remove the short circuit chip will lead to overheating of the brake resistor MITSUBISHI 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 MITSUBISHI INSTRUCTION MMANUAL FR-A740-75K-CHT 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.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Input and output points: 96 points MITSUBISHI INSTRUCTION MANUAL.
Input points: 48 points.
Input specification: leakage type.
Output points: 48 points.
Output form: transistor output (drain).
Power consumption: 14W.
Weight: 0.35KG.
Outline dimension: 85.4x90x87mm.
Hard and compact type third generation micro programmable controller.
Connector type input and output type provincial connection.
Greatly strengthened the industry''s highest level of high-speed processing and positioning and other built-in features.
High cost of the province space models.
FX3UC in the province of space, the province also greatly strengthened the connection of high-speed processing and positioning and other built-in features.
The host is built in DC24V power supply, the connector input and output form of the transistor output.
In addition, according to the product mix can also achieve network communications, analog control, data collection and other functions FR-A740-75K-CHT INSTRUCTION MANUAL.
Third generation high function micro programmable controller.
Connector type can save space, province wiring FR-A740-75K-CHT Manual.
Built in high speed processing and positioning.
Ultra small size, control points to 256 points.
Construction of CC-Link remote I/O 384 points.
