Power: 280kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose MITSUBISHI INVERTER Instruction manual. ) Power: 7.5kw FR-F740-3.7K-CHT
Voltage: 400V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5.5 to 37kW. MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 18.5kw.
SLD converter rated current: 93A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have MITSUBISHI INVERTER Instruction manual.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equipment) MITSUBISHI INVERTER Instruction manual.
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network FR-F740-3.7K-CHT Instruction manual.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps FR-F740-3.7K-CHT Instruction manual. Power: 1.5kw.
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 FR-F740-3.7K-CHT 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 degreees C or higher, it is necessary to take protective measures and cooling FR-F740-3.7K-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 thhe short circuit chip, in addition to connecting the DC reactor MITSUBISHI INVERTER Instruction manual.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
