The frequency of a transducer can be set by a digital signal from an external BCD or binary code.
BCD code 3 (maximum 999).
BCD code 4 (maximum 9999).
Binary code 12 (max FFFH).
Binary code 16 (max FFFFH). Power: 1.5kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted FR-F720-S75K Instruction manual.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed FR-F720-S75K Does not remove the short circuit chip will lead to overheating of the brake resistor.
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 FR-F720-S75K Instruction 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. MITSUBISHI inverter series: FR-F840 FR-F720-S75K Instruction manual.
Voltage level: three phase 400V.
Power: 220kw.
SLD converter rated current: 481A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drivve motor FR-F720-S75K Manual .
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-F720-S75K Manual .
