Additional specifications and description
Where is this frequency inverter typically used?
FIHV series are general purpose frequency inverters, designed to control three-phase 400 Volt motors in HVAC and industrial applications. Typical applications include supply and extract fans, air handling units, centrifugal pumps, circulation pumps, cooling towers, smoke extraction systems and conveyor systems. By matching the motor speed to the actual demand, energy consumption, noise levels and mechanical wear are significantly reduced.
Why is this inverter easy to commission?
The FIHV series has been designed with ease of use in mind. Default settings are suitable for many standard applications and only a limited number of parameters are required for basic commissioning. Application macros simplify the configuration process even further. The drive also features status LEDs, a QR code that provides direct access to online support information and USB-C connectivity for fast parameter configuration and diagnostics using Optitools software. Parameters can also be copied between drives, reducing commissioning time for larger installations.
Which motor types can be controlled?
This frequency inverter operates from a three-phase 400 Volt supply and controls a wide range of motor technologies. In addition to conventional induction motors, it supports permanent magnet (PM), brushless DC (BLDC), synchronous reluctance (SynRM), line-start permanent magnet (LSPM) and Permanent Magnet Assisted Reluctance (PMAREL) motors. Advanced sensorless vector control ensures stable speed regulation, high starting torque and smooth operation across the complete speed range, while motor efficiencies above IE5 can also be supported.
Why does a frequency inverter save energy?
Unlike a conventional speed controller, a frequency inverter regulates both the motor voltage and motor frequency. This allows the motor to operate at its optimum efficiency over the entire speed range. Especially in fan and pump applications, even a small reduction in motor speed results in substantial energy savings. Integrated PI control, sleep mode and process control functions enable the drive to automatically adjust the motor speed to the actual demand, further reducing energy consumption.
What makes the FIHV series different?
Compared to previous generations, the FIHV series offers several additional functions as standard. It features integrated Safe Torque Off (STO) certified to SIL3, an internal brake chopper, onboard diagnostics with fault history, programmable analogue and digital I/O, a 24 V keep-alive supply, support for side-by-side installation and operation in ambient temperatures up to 50 °C without additional cooling. These features make the FIHV series suitable for both new installations and demanding retrofit projects where reliability, safety and ease of maintenance are important.
Safe Torque Off
Safe Torque Off or STO is a certified safety function that safely disables the motor torque without disconnecting the mains supply. The communication (networks) also continue to function normally while the motor is stopped safely. This simplifies integration into emergency stop and machine safety circuits while keeping the inverter electronics powered for diagnostics and a faster restart after the safety condition has been cleared.
Why is the integrated EMC filter important?
Frequency inverters switch high currents at high frequencies, which can generate electromagnetic interference (EMC). The FIHV therefore includes a built-in Category C1 EMC filter as standard, helping to reduce conducted emissions, simplify installation and improve compliance with EMC requirements. Correct cable routing and installation practices further minimise interference and ensure reliable operation of the complete installation.
