HDS03.2-W100N-HS98-01-FW

The HDS03.2 series delivers about 50 A at 4 kHz and 35 A at 8 kHz continuous current, since increasing switching frequency reduces available current due to switching losses. Using higher frequencies improves motion smoothness and reduces torque ripple, but requires derating of current and heat-management.

SERCOS provides deterministic, digital communication with precise timing and synchronization, which improves multi-axis coordination over analog signals subject to drift and noise. For high-speed coordinated moves (robotics, packaging machines), SERCOS reduces jitter and allows tighter coupling among drives.

At 8 kHz, switching losses (in IGBTs or power electronics) increase, which raises internal temperatures and reduces efficiency, limiting continuous current to ~35 A; whereas at 4 kHz the losses are lower, allowing ~50 A. If heat dissipation (cooling, airflow) is constrained, staying at lower switching frequencies can extend reliability.

The manufacturer’s data indicates installation up to ~1,000 meters above sea level without performance loss; above that, air density drops, reducing cooling efficiency and possibly requiring derating. In high‐altitude installations, ventilation and blower performance must be verified to ensure adequate heat removal.

Insulation Class C (as per DIN VDE/IEC) allows higher upper temperature limits for insulation materials (to handle more thermal stress). It means the unit can tolerate higher internal temperatures before insulation breakdown, but wiring and motor insulation should match or exceed this standard for reliable operation.
