Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700.
Power: 15kw.
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 FR-A7NC.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table
FR-A7NC
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 MITSUBISHI FR-A7NC.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Power: 30kw.
Voltage: 200V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter MITSUBISHI FR-A7NC.
Three types of discharge resistors are available.
Please select according to the required braking torque. MITSUBISHI inverter series: FR-A800.
Voltage level: three phase 400V.
Power: 355kw.
SLD converter rated current: 866A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
To maximize the performance of the motor.
Advanced auto tuning function.
The newly developed PM motor auto tuning feature can be used to operate other manufacturers of PM motors (Yong Ci synchronous motors) in the sensorless state.
Not only can drive MITSUBISHI induction motor and PM motor, but also cann drive other manufacturers of induction motor and PM motor FR-A7NC.
This means that you can reduce the cost of inventory and supplies.
If the PM motor is produced by a IPM motor or other company using MM-CF, the starting torque is limited to 50%,
EEven after tuning is not simple to use and positioning control of zero speed torque) induction motor and permanent magnet motor can be combined freely FR-A7NC.
