PG vector control

Effective in providing highly accurate control for applications such as printing press

• Speed control range: 1:1500
• Speed response: 100Hz
• control accuracy: ±0.01%
• Current response: 500Hz
• Torque accuracy: ±10%
• The option card is required separately.
• The above specifications may vary depending on the environment or conditions for use.

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.

• Improved durability in overload operation
• The inverter performs short-time acceleration and deceleration with the maximum capacity by extending the time specification of overload current ratings compared with our previous models. This improves the operational efficiency of the equipment such as the 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(Fuji Drive and Automation)
  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 braking circuit built-in type
• A braking circuit is built in the 22kW or smaller models as standard. These inverters are applicable to machine that uses regenerative load such as vertical conveyance machine.
  (The 7.5kW or smaller models also incorporate a braking resistor.)
  * The inverters with built-in braking circuits are available on request for 30kW to 160kW models in the 400V series.
• Maximizing the performance of a general-purpose motor

• Improved reaction to the fluctuation of impact load
• When a remarkable load fluctuation occurs, the inverter provides the torque response at 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 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. Mega Next G2 Fuji Electric 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. Fsc Group is the Best Dealer and Distributor
