“•The “”F700P inverter for fans and pumps”” can drive both general-purpose motors
(3-phase induction motors) and IPMmotors. The F700P could be thesolution to your energy saving need”            
            
(1) Energy saving with speed con            
” The consumed power of a variable-torque load, such as fans, pumps, and blowers, is proportional to the cube of its rotation speed.
This means that controlling the rotation speed to adjust the air volume
can lead to energy savings”            
            
(2) Energy saving with Optimum excitation control (General-purpose motors)            
” Optimum excitation control continuously adjusts the excitation
current to an optimum level to provide the highest motor efficiency, and that leads to substantial energy savings. ”            
            
(3) Energy saving with IPM motors            
•High efficiency achieved with IPM motors            
The IPM motors that have permanent magnets embedded in their rotors            
are even more efficient than the high-performance energy-saving motors.            
            
(4)Various Functions for Fans and Pumps            
     (1) Variable-torque acceleration/deceleration pattern            
     Variable torque loads suchas fans and blowers can be accelerated/decelerated in a short period of time.            
            
     (2) Full-scale PID function            
     To save energy in low-speed operation: PID output shutoff (sleep) function            
     To shorten the start-up time of PID control: PID automatic switchover function            
     For air conditioning applications: Forward/reverse rotation switching by external signals            
     To use various types of detectors: PID set point and measured value outputs in            
     voltage (0 to 5V / 0 to 10V) and current (4 to 20mA)            
            
      (3) Complete I/O terminals come standard            
      Contact input (12 terminals), analog input (3 terminals), open            
      collector output (5 terminals), relay output (2 terminals), analog            
      output, and pulse train output come standard. Various functions            
      can be assigned to these terminals.            
      Voltage and current are selectable for analog input.            
      ON/OFF status of the signals inputted to or outputted from th  I/O terminals can be displayed on the operation panel.            
                 
     (4) Automatic acceleration/deceleration time switchover            
”      A frequency where the acceleration/deceleration time is changed can be pre-set; an
      external switch is not required to switch the time setting. This function is especially
      useful for an operation thatrequires high torque in alow speed operation”            
     (5) Password function            
     Parameter writing/reading can be restrictedwith a 4-digit password.            
     This function is useful to prevent parameter values from being rewritten by misoperation            
            
     (6) Keep running during instantaneous power failure            
     Automatic restart after instantaneous power failure function / flyinstart function.            
     After an instantaneous power failure, the operation is re-startable from the coasting motor speed.            
     Even if the rotation direction has been forcibly reversed, the operation can be            
     smoothly restarted in the original direction.            
     Power failure time deceleration-to-stop function.            
     During operations of fans and blowers, the operation is continued at an            
     instantaneous power failure without the motor coasting            
            
    (7) Energy saving effect checked at a glance            
    The energy saving effect can be checked on the energy saving monitor.            
    The measured output power amount can be output in pulses.         

Compact size inverter with reasonable price
General-purpose magnetic flux vector control
General-purpose magnetic flux vector control and auto tuning functions are available.
These functions ensure the applications that require high starting torque, such as
washing machines, agitators, and transfer machines including conveyors, hoists,
and elevators.
• High torque of 150% / 1 Hz is realized (when the slip compensation function is valid).
• Auto tuning
With our “non-rotation” auto tuning function the motor constant (R1) can be
automatically calculated.
High performance
Brake unit connection
Brake unit can be connected using terminal P/+ and terminal N/-.
It is useful for applications require regenerative braking torque
during deceleration, such as transfer machines and food machines.
Optimum excitation control
The excitation current is constantly adjusted to its optimum value to drive the
motor most efficiently. With a small load torque, a substantial energy saving
can be achieved.
