Higher switching frequency increases switching losses, so at 8 kHz the unit can only sustain 80 A continuously, meaning in high dynamics tasks you may need to derate or ensure cooling is superior.

Because of the ~800 W loss, install with sufficient clearance around blower inlets and exhausts, ensure cabinet air exchange is high, and avoid nearby heat sources—otherwise ambient temp rise will severely reduce component lifetime.

Insulation class C allows higher temperature tolerance of winding insulation and components (higher thermal stress), so the drive can operate under more severe ambient temperature swings without immediate insulation breakdown.

Though 30 W is small relative to losses, it still contributes to the internal heat and must be included in the local power supply and cooling load calculations, especially in systems with many drives or tight power margins.

Large torque or rapid acceleration demands push current near or above continuous ratings briefly, causing high transient currents and thermal spikes; ensure DC bus supply and overcurrent protection accommodate those peaks, and verify that cooling and thermal mass can absorb these transients without damage
