Frenic- Mega G2

Same Mounting Dimensions

• External and mounting dimensions are fully compatible with the G1 Series.
• Makes G2 a direct drop-in replacement for existing G1 installations.

New Operation Keypad (Touch Panel)

• Standard keypad: 7-segment, 5-digit LED display, shift key for cursor control, [M] LED display to monitor digital output signals.
• Multifunctional keypad: LCD display supporting 19 languages (including Japanese hiragana, katakana, kanji), clock function with alarm history timestamps, SD card slot for traceback data, built-in Bluetooth for remote parameter changes and diagnostics via mobile device, USB port, and IP55-rated waterproof front and side surfaces.

Improved Control Performance

• Comes standard with synchronous motor drive, compatible with Fuji's induction motors (Premium Efficiency IE3 / Standard Efficiency IE1), various synchronous motors, and other manufacturers' motors.
• Maximum output frequency increased from 500 Hz (G1) to 599 Hz (G2), useful for machine tools and automotive testing equipment.
• Current response improved from 500 Hz (G1) to 1000 Hz (G2); speed response improved from 100 Hz to 200 Hz (with high-speed sensor), reducing rotation irregularities in metalworking and wire-drawing machines.
• Speed control range expanded, vector control with high-speed sensor now reaches 1:1500 (induction motor) vs. 1:1500/1:1000 on G1; constant torque and output area ratio improved to 1:16 (with sensor), benefiting press machines and conveyance machines.

Standard Safety Functions

• Conforms to EN ISO 13849-1:2015 (Cat.3/PL:e) and IEC/EN 61800-5-2:2016 (SIL3, Functional Safety: STO).
• Built-in function to adapt to machine safety standards, simplifying main circuit switching device design for safe stoppages.

Simple Wiring

• Control terminal block was upgraded from 35 poles (G1) to 44 poles (G2), using an industry-standard rod-shaped terminal type.
• Nine additional terminals ease wiring work; G1's round terminal type can still be mounted for compatibility.

Easy Parameter Migration

• Compatibility mode allows parameters read from a G1 unit (via keypad or PC loader) to be written directly to a G2 unit , no manual re-entry needed.

Enhanced PC Loader Functions

• Connect the keypad directly to a PC via USB (mini B) cable.
• Store and check inverter information at the office, or diagnose issues on-site using a remote keypad capable of writing to keypad memory.

Improved Environmental Resistance

• Ambient operating temperature raised to +55°C (derating required at 50°C or higher).
• Strengthened PCB coating (JIS C 60721-3-3 / IEC 60721-3-3 Class 3C2).
• IP55 protection for the inverter's main cooling unit (supports 30 kW to 630 kW models), enabling enhanced cooling outside the panel.

Various New Application Features

• Positioning Function (New): High-precision positioning control via pulse string input and feedback output. Includes 8 positioning data points, pulse train instruction, origin return function, overtravel detection, and position preset function, shortens machine tact time.
• Orientation Function (New): Enables rotator positioning and servo-locks machinery in place after stoppage.
• PID Auto Tuning (New): Automatically adjusts proportional and integral gains, shortening system start-up time.
• Load Limiter (New): Stops the system when excessive torque is detected; allows operation only in the direction opposite the excessive load.
• Load Adaptive Control (New): Runs the system at a ratio-multiplied frequency when actual load is below the configured level, improving efficiency.
• Customizable Logic Functions (Enhanced): 260 programming steps, 55 digital and analog logic symbol types (counters, timers, arithmetic operations, comparators, limiters, selectors, holders). No external PLC or relay/timer hardware needed, free programming tool downloadable from Fuji Electric's website.
• Supports a Variety of Networks (Option Cards): Up to 3 option cards can be inserted (A-Port, B-Port, C-Port). Supported protocols: DeviceNet, CC-Link, T-Link, PROFIBUS-DP, CANopen, SX bus, and Ethernet (Ethernet/IP, PROFINET RT, Modbus-TCP, BACnet/IP, EtherCAT, coming soon).
• Enhanced Network Functions: Standard RS-485 terminal (in addition to the RJ-45 keypad port) supports multi-drop terminal connections.
