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 FX3U-128MT/ES-A Positioning Control Edition Manual FX3U-128MT/ES-A USER'S MANUAL FX3U-128MT/ES-A
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.
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 FX3U-128MT/ES-A Positioning Control Edition Manual FX3U-128MT/ES-A USER'S MANUAL. MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 15KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy FX3U-128MT/ES-A Positioning Control Edition Manual FX3U-128MT/ES-A USER'S MANUAL.
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements. If can use: closed loop vector control; spindle positioning, position control, speed control, servo lock zero.
Suitable frequency converter: FR-A700. 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 transffer function FX3U-128MT/ES-A Positioning Control Edition Manual FX3U-128MT/ES-A USER'S MANUAL.
Protective switch with incidental write protection,
Program transfer function between built-in PLC and memory box.
When the memory box is installed on thee PLC host, the program in the memory box is preferred FX3U-128MT/ES-A Positioning Control Edition Manual FX3U-128MT/ES-A USER'S MANUAL.
The memory box can be installed on the function expansion board and FX3S-CNV-ADP, FX3G-CNV-ADP.
