1.1 Features
Upgraded FRENIC-Mini (FRNC2-) functions
• Dynamic torque vector control providing bumped-up torque performance
Fuji's original dynamic torque vector control broadens the range of applications.
• RS-485 communications port provided as standard to facilitate system configuration
While the original FRENIC-Mini series has an RS-485 communications port as an option, the
upgraded one has it as standard, making it easy to connect the upgraded one to a PLC and facilitating
system configuration.
• Slow flowrate stop function under PID control for further energy saving
Under PID control for constant pump discharge pressure, the slow flowrate stop function stops the
inverter when the pump discharge pressure is high, which achieves further energy saving.
• Braking signal function making the FRENIC-Mini applicable to simple vertical lift
applications
The upgraded FRENIC-Mini series supports brake ON/OFF signals that are conventionally supported
by the upper inverter series only. The braking signal function enables the FRENIC-Mini to be applied
to simple vertical lift applications.
• Motor switching function
Turning the Di terminal ON and OFF switches between parameters specified for the 1st motor and
those for the 2nd motor. This further broadens the range of applications.
• Motor auto-tuning
The auto-tuning function enables the dynamic torque vector control, automatic energy saving
operation, and other advanced motor controls to be applied also to non-Fuji general purpose motors.
• Long-life DC link bus capacitors, control printed circuit board capacitors and cooling fans
adopted
• Optional USB-equipped remote keypad
Data copying and connection to FRENIC Loader are easy.
• Permanent magnet synchronous motor (PMSM) supported
A PMSM is more efficient than an induction motor (IM) so that further energy saving can be achieved.
• Available capacity range up to 15 kW (20 HP)
The capacity range has been spread.
