Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 2.2kw.
SLD converter rated current: 5.2A.
Structure and function: Standard model.
Type: CA FR-A720-1.5K Applied Manual FR-A720-1.5K INSTRUCTION MANUAL.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed FR-A720-1.5K
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor FR-A720-1.5K Applied Manual FR-A720-1.5K INSTRUCTION MANUAL.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. Memory type: EEPROM.
Protection switch: have.
Program transfer function.
EEPROM memory can be connected to FX3SA, FX3GA, FX3GE do not need a battery backup and with the program transfer function FR-A720-1.5K Applied Manual FR-A720-1.5K INSTRUCTION MANUAL.
Protective switch with incidental write protection,
Program transfer function between built-in PLC and memory box.
When the memory box is installed on the PLC host, the program in the memory box is preferred.
The memory box can be installed on the function expansion board and FX3S-CNV-ADP, FX3G-CNV-ADP. Power: 0.4kw.
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 FR-A720-1.5K Applied Manual FR-A720-1.5K 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 thhe short circuit chip, in addition to connecting the DC reactor FR-A720-1.5K Applied Manual FR-A720-1.5K INSTRUCTION MANUAL.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
