G1 Series General Vector Frequency Inverter for Motor Control
The G1 Series General Vector Frequency Inverter is a variable frequency drive range covering 0.75kW to 500kW, with V/F control, open-loop vector control and model-specific motor control functions.
The G1 Series is a general vector frequency inverter range developed for industrial motor control. The original brochure describes V/F control and open-loop vector control (SVC), together with control functions for different motor operating requirements.
The product range covers 0.75kW to 500kW. The published technical tables include G-type configurations for general loads and P-type configurations for fans and pumps, with model-dependent power and current ratings.
Documented functions include multiple digital and analogue input/output terminals, built-in PID control, multi-speed control, Modbus communication, braking functions and electrical protection features.

PRODUCT FEATURES
G1 Series Motor Control Functions
V/F and Open-Loop Vector Control
The G1 Series supports V/F control and sensorless open-loop vector control. The brochure specifies 150% starting torque at 0.5Hz under SVC operation.
Digital and Analogue I/O
The documented interface includes seven digital inputs, two analogue inputs, two analogue outputs, one programmable digital output and two relay outputs.
Built-In Control Functions
The technical brochure describes built-in PID control, simple PLC functions with up to 16 speeds, torque limiting and acceleration/deceleration settings.
Braking Functions
The manufacturer lists flux braking, stop DC braking and dynamic braking among the supported braking functions.
Protection Functions
The brochure describes three-phase current detection, output phase-loss and imbalance protection, earth short-circuit protection, automatic current limiting and overvoltage stall control.
Modbus Communication
Standard Modbus communication is documented, together with selectable command and frequency-setting channels.
