- Description
Description
The INVT GD28-004G-4 belongs to the “GD28 Series Flexible General-Purpose VFD” line from INVT. According to the official catalogue:
-
It is designed to provide general motor control (both light and heavy loads) with a compact footprint, strong safety features and flexible communications.
-
The “004G” in the model number indicates a 4 kW constant-torque output rating (in the 380-480 V / 3-phase class) for this series.
-
The “-4” at the end of the model number designates the input voltage class: AC 3-phase, 380–480 V.
-
Frame B refers to the physical size category for this power class in the GD28 series, offering a mid-sized installation footprint suitable for control panels.
-
Key integrated features of the series (and thus this model) include: built-in braking unit, STO (Safe Torque Off) safety function (SIL3 / PL e), integrated EMC filter options, Type-C PC interface for parameter setup, side-by-side mounting without spacing (for Frame A/B) and compatibility with multiple industrial protocols.
Key Features
Here are some of the standout features you should highlight:
-
High performance motor control: Supports both V/F control and sensorless vector control (SVC), enabling efficient operation even for demanding applications.
-
Built-in safety & compliance: The STO safety function ensures safe operation and maintenance. The product meets major international certifications (CE, UL) and EMC standards (C2/C3) depending on model.
-
Compact installation: For Frames A & B the series supports seamless side-by-side installation without required spacing in typical ambient conditions <40 °C, helping save cabinet space.
-
Smart commissioning interface: A built-in USB Type-C port (in some models) allows easier parameter setup and monitoring from a PC without needing special adapters.
-
Flexible connectivity: Standard Modbus RTU communication, with optional expansion cards for PROFINET, EtherNet/IP, EtherCAT etc., enabling integration into modern industrial networks.
-
Durable design: The product supports full-load operation up to ambient 50 °C and uses reinforced PCB coatings meeting 3C2 / 3S2 environmental standards.
