MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 110KW.
Frequency converter common frequency of a given way: the operator keyboard is given, the contact signal given, analog signal given, the pulse signal given and communication methods given, etc..
These frequencies have their advantages and disadvantages, and should be selected according to the actual needs.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions.
MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 55kw.
SLD converter rated current: 316A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on MITSUBISHI FR-F740-S110K-CHT
FR-F740-S110K-CHT
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units MITSUBISHI FR-F740-S110K-CHT.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. 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 MITSUBISHI FR-F740-S110K-CHT.
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-F740-S110K-CHT MITSUBISHI.
MYS type resistor can be used. But please pay attention to the allowable brake use rate FR-F740-S110K-CHT MITSUBISHI.
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-A820.
Voltage level: three phase 200V FR-F740-S110K-CHT MITSUBISHI.
Power: 18.5kw.
SLD converter rated current: 93A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
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-AA700 series, to reduce the volume of equipment) FR-F740-S110K-CHT.
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 MITSUBISHI FR-F740-S110K-CHT.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
