Designed for precise speed and torque control of three-phase asynchronous motors, the Lenze EVF8243-E frequency inverter integrates seamlessly into centralized control cabinet architectures. This robust 2HP (1.5 kW) drive operates on a 460V nominal supply, delivering reliable dynamic performance in demanding industrial environments. As part of the legacy 8200-series modular frequency inverter range, it features a compact footprint and flexible communication options via pluggable function modules.

The EVF8243-E belongs to the legacy 8200 Vector family. For modern retrofits, the Lenze i550 series or 8400 StateLine drives are the recommended migration paths, though parameter conversion is required as register maps differ.
When operating in high ambient temperatures (above 40 degC), derating of the continuous output current is mandatory. Ensure adequate clearance at the top and bottom of the drive (minimum 100 mm) to prevent thermal tripping under continuous heavy loads.
Parameterization requires either the EMZ8201BB keypad module or the LECOM communication module connected to a PC running Global Drive Control (GDC) software. Always use shielded motor cables with 360-degree EMC grounding clamps to prevent high-frequency interference with nearby analog sensor signals.
DANGER: HAZARD OF ELECTRIC SHOCK OR ARC FLASH. Disconnect all power sources before servicing the drive. Wait at least 5 minutes after de-energizing to allow internal DC bus capacitors to discharge to safe voltage levels (< 50 VDC) before touching any electrical terminals.
