Drive: MR-H_ACN series CC-LINK features.
Rated output: 22KW.
The test system is composed of two parts, namely, the servo driver, the motor system and the host computer.
The host computer sends the speed command signal to the servo driver,
Servo drives start to run in accordance with the instructions MITSUBISHI MR-J20A1.
In the course of operation, the running data of the servo system is collected by the host computer and the data acquisition circuit,
And carries on the preservation, the analysis and the display to the data MR-J20A1 Because the motor is not loaded in this test system,
So compared with the previous two kinds of testing systems, the system has a relatively small volume,
And the measurement and control circuit of the system is relatively simple,
But it also makes the system can not simulate the actual operation of the servo drive MITSUBISHI MR-J20A1.
Usually, such testing system is only used to test the rotational speed and angular displacement of the tested system under no-load condition,
And can not carry on the comprehensive and accurate test to the servo drive MITSUBISHI MR-J20A1. Power: 7.5kw.
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.
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.
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.
Voltage level: three phase 400V.
Power: 45kw.
SLD converter rated current: 93A.
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 operatingg characterisstic drive motor MR-J20A1.
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).
Othherr manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving MR-J20A1.
