FRN0.75G1S-4C 380V0.75KW High Performance FujifilmFrequency converters
FRENIC-MEGA new generation inverter G1S series, can replace the original G11S series, higher standards, closer to European standards
It has the following characteristics:
● PG vector control
Suitable for applications that require high-precision positioning control, such as offset printing machines.
●Improved Fuji Electric Corporation's unique dynamic torque control performance
Dynamic torque vector control is an advanced technology unique to Fuji Electric Corporation. In the dynamic torque vector control, the voltage error of the main circuit device of the motor is fully considered, and the motor constant setting and new magnetic flux monitoring are equipped to achieve a high starting torque of 200% even at a low speed of 0.3Hz.
●Improve overload tolerance
Compared with Fuji Electric Corporation's conventional products, by extending the overload rating time, the maximum number of acceleration and deceleration functions in a short period of time has been realized, thereby improving the efficiency of cutting and handling machinery.
●Overload tolerance: 200%-3 seconds/150%-1 minute
●Increase the power of models with built-in brake resistors
In models up to 22kW, a built-in brake circuit is standard and is suitable for upward and unloading devices that are more used for regenerative loads.
(Built-in braking resistor at 7.5kW or less)
※If you want to further increase the power, you can order a model with 400V: 30kW~110kW.
●Maximize the performance of general-purpose motors
● Sensorless vector control
It is suitable for applications with high starting torque such as hanging basket type three-dimensional parking garage.
●Improved shock load response capability
Advanced torque response to sharp load changes is realized. By controlling the magnetic flux, the change in the motor speed is controlled to a minimum, so that the vibration is controlled. It is ideal for equipment that requires stable speed, such as cutting machinery.
●Improve the response performance to operation commands
The response to the operation command terminals, which have been highly evaluated in the past, has been further improved, and the response time has been achieved for the shortest time.
The interval between cycles is shortened, making it suitable for operation with a lot of repetitive operation.
Equipped with USB interface to make information management easier by flexibly using PC software (when remote operation panel is selected)
● In the memory of the operation panel, various information of the inverter body can be saved, and confirmation work can be carried out without selecting a location.
● At the production site, information can be sent directly to the computer (PC loader) through the USB interface of the operation panel.
● Regular life information collection can be carried out efficiently.
● Through the real-time scanning function, it can confirm the abnormal situation of equipment and machinery.

(3) Fault history information (last 4 times)
(4) Maintenance of information
(5) History tracking (recent configuration)
Wide range of uses
●It has a function that facilitates the work of speed command
Speed control commands can be issued by using an input pulse train (single-phase pulse + command symbol) such as a pulse generator.
(Maximum pulse input 100kHz)
● Configure ratio operation
This function is suitable for adjusting several conveyor systems. The frequency command ratio of several driven axes can be set relative to the main speed. The handling speed of conveyors with varying loads can be easily adjusted.
●Complete brake circuit protection function
By monitoring the action of the brake transistor, the brake resistor can be protected. A dedicated signal is output when an abnormal brake transistor is detected. Using these signals, the protection function can be activated by setting the circuit that cuts off the input power outside the frequency converter.
●Function to prevent items from slipping
In the process of handling up and down, etc., the accuracy of the brake signal is improved. By adding the torque value to the current value and frequency that were previously monitored when the brake signal is output, the braking sequence can be easily adjusted.
●Pendulum control function that is most suitable for winding
Compare the target value with the feedback value, and add or subtract the PID result from the base speed. Since the gain (proportional band) of the PID calculation part can be set low (wide), it can be applied to automatic control systems that require rapid response such as speed control.
●Rich in functions and versatile
(1) Analog input: with 2 voltage inputs (with polarity) and 1 current input (2) with
Low water stop function (when the amount of water is small, it can be pressurized before stopping) (3) Broken line V/f mode 3 points (4) With analog fault output function (5) Can be selected to the 4th motor (6) S-shaped acceleration and deceleration range setting (7) PID feedback wire break detection
●Positioning control (PG option card)
It has functions that are ideal for applications that require high-precision positioning, such as handling machinery. Through the position controller (APR) + PG vector control, the position control accuracy is greatly improved. Due to the shorter positioning time, it is beneficial to reduce the interval period.
●Logic input and output can be easily completed by parameter setting. The surrounding circuitry has been simplified.
With servo lock function (PG option card)
●It is suitable for the stop timing and brake torque adjustment when the motor position is positioned in handling machinery. It has a convenient function to add torque from the outside during stopping and when torque maintenance is required. Shorten cycle times by shortening deceleration times.
