Specifications
Rich Configuration
The built-in C2 filter version perfectly meets
European market requirements, saving cabinet space and reducing costs. Supports various operator types, including optional LCD and LED keypads, and can also be equipped with externally mounted LED or LCD keypads for operation.01
Safe and Reliable
Standard STO function meets SIL3
safety integrity level certification, preventing unintended motor startup when the elevator is stopped, ensuring safer operation. The electronic star sealing function is implemented through the VFD’s internal circuitry, enabling fast response and reducing elevator failure rates. A wide voltage range with strong grid adaptability helps prevent faults caused by power fluctuations.02
Powerful Functions
10s for 200% overload capacity exceeds that
of many competitors, reducing the likelihood of overload faults. Two additional S-terminals support inspection and emergency operation modes. Two emergency power input channels eliminate the need for external switching circuits. Secondary development capability is supported, helping customers enhance after-sales and maintenance value.03
Flexible and User-Friendly
By connecting to INVT Workshop software,
users can collect real-time elevator waveform data, perform analysis, and access various commissioning and diagnostic functions, making troubleshooting easier. Local USB program upgrades enable faster and more convenient updates.04
