The compact design of the GD28 Savings to to 35 % Switchgear cabinet gstandard installations and thus enables uncomplicated integration into existing or new plant concepts. The protection type IP20 ensures, in addition, a contact-resistant assembly in the switchgear cabinet. The converter additionally convinces by a permissible ambient temperature of -10°C to to +60°C (HD) in full load operation and a permitted storage temperature of -20°C to +70°C. In environments with temperatures below 40°C, the rowing without distance (side-by-side assembly) enables a considerable reduction in the space requirement in the switchgear cabinet.
Efficient and precise control for your processes
The GD28 features powerful, sensorless vector control (SVC), which is an impressive feature even at low speeds. Start-up torque from up to 200 % at 0,5 Hz achieved. These are: High-precision torque control Ensure efficient, dynamic and precise motor control, making it ideal for applications where machining quality and process stability are critical.
Supported regulatory procedures
Sensorless Vector Control
Linear, quadratic and 5-point characteristic
Dynamic energy-saving characteristic curve
three-phase asynchronous motor
Permanent magnet synchronous motor
An integrated Brake chopper allows safe and fast braking by using an optional brake resistance. This makes the GD28 ideal for demanding tasks in conveying technology, machine tools, packaging machines and pump and fan applications.
By default, the secure Two-channel STO (Safe Torque Off), certified according to SIL3/PL in accordance with IEC61800-5-2. This function guarantees safe torque disconnection in critical situations and enables safe maintenance. The frequency inverter also meets all relevant international standards and certifications such as CE, UL, CCS and TÜV.
To effectively minimize electromagnetic interference, the GD28 is equipped with an integrated EMV filter Class C2/C3 Equipped to ensure trouble-free integration in industrial environments.
For modern industrial applications, the GD28 offers standard Modbus RTU and Optional communication interfaces such as: PROFINET (supports MRP & S2), EtherCAT (supports EoE), UDP, Ethernet/IP (supports DLR) or Modbus TCP. Two RJ45-Anschlüsse Enable fast network integration, remote access and easy diagnosis via Ethernet.
The assembly and maintenance are carried out by screwless spring clamps and a Plug-in fans much easier. This is Reduces the time required for installation and maintenance up to 50 %. The intuitive user guidance and a fast Parameterisation over the USB-C connection, without the mains voltage being required, make the GD28 particularly user-friendly.
