FUJI FRENIC-MEGA Series High Performance Inverters

FRENIC MEGA is the new High Performance inverter from Fuji Electric and is the successor of G11S drive. 
The capacity range of FRENIC MEGA is for 3 ph 400 V supply from 0.4 kW to 630 kW and for 3 ph 200 V supply 
from 0.4 kW to 110 kW. The overload capacity of FRENIC MEGA is 150% for 1 min and 200% for 3s (in High Duty mode).

The inverters with capacities of 5.5 kW and above can be used in dual rating; this means that the same inverter 
can be used for next higher capacity (in Low Duty mode). For example a 5.5 kW inverter can be used for a 7.5 kW motor;
in this case the overload is 120% for 1 min. The braking transistor is included as standard up to 22 kW units 
and is optional up to 110 kW units. The braking resistor is included as standard up to 7.5 kW units.

Ideal for highly accurate control such as positioning

PG vector control 
Effective in providing highly accurate control for applications such as printer

Fuji's original dynamic torque vector control has further evolved

Besides the dynamic torque vector control, the inverter is equipped with the motor constant tuning for compensating even a voltage error of the main circuit devices and the magnetic flux observer of a new system. This realizes a high starting torque of 200% even at a low-speed rotation of 0.3Hz.

Fuji's original dynamic torque vector control has further evolved

The inverter performs short-time acceleration and deceleration with the maximum capacity by extending the time spec of overload current ratings compared with our previous models. 
This improves the operation efficiency of the equipment such as cutting machine or conveyance machine.
Overload durability: 200% for 3 sec and 150% for 1 min.

The standard model is available in two specifications concerning the operation load.

Classification Overload current rating Major use
HD (High duty) spec 200% for 3 sec, 150% for 1 min Operation under heavy load
MD (Middle duty) spec 150% for 1 min Operation under constant torque load
LD (Low duty) spec 120% for 1 min Operation under light load

Expanded capacity for the brake circuit built-in type

A brake circuit is built in the 22kW or smaller models as standard. These inverters are applicable to the machine that uses regenerative load such as a vertical conveyance machine. 
(The 7.5kW or smaller models also incorporate a braking resistor.) 
* The inverters with built-in brake circuit are available on request for 30kW to 55kW models in 200V series and 30kW to 110kW models in 400V series.

Maximizing the performance of a general-purpose motor

Speed sensor-less vector control  
Useful for the application that requires a high starting torque, such as the gondola type
multi-level car parking towe

 

 

Improved reaction to the fluctuation of impact load

When a remarkable load fluctuation occurs, the inverter provides the torque response in the class-top level. . It controls the flux to minimize the fluctuation in the motor speed while suppressing the vibration. This function is best suited for the equipment that requires stable speed such as a cutting machine 

Quicker response to the operation commands

The terminal response to the operation commands has had an established reputation. FRENIC-MEGA has further shortened this response time, achieving the industry-top response time.
This function is effective in shortening the tact time per cycle and effective for use in the process including frequent repetitions. 

For the various consumable parts inside the inverter, their designed lives have been extended to 10 years, which also extended the equipment maintenance cycles.

Consumable part Designed life  
Main circuit capacitor 10 years an ambient air temperature of 40°C
Electrolytic capacitor on PCB 10 years

and under the load rate of 100% (HD spec) o r80% (LD spec)

 

 

Cooling fan 10 years  

HD : High Duty spec 200% for 3 sec, 150% for 1min 
MD : Middle Duty spec 150% for 1min
