Frequently Asked Questions

What is the continuous output current for the Bosch Rexroth Indramat HMS01.1N-W0150-A-07-NNNN, and how does it impact thermal management?

The continuous current is about 99.7 A, which means the internal blower and enclosure design must dissipate the heat generated by ~150 A peaks without compromising reliability. Proper airflow, ambient temperature control, and avoiding hot spots are critical for maintaining performance.

How does the input voltage range of 254-750 V DC affect compatibility in multi-axis drive systems?

This wide range enables the HMS01.1N unit to work with many common DC bus supplies or regenerative converters without additional voltage converters. It also introduces design margin for voltage drops in wiring or interconnects, which must be accounted for to avoid undervoltage cutoffs.

What are the performance implications of the output frequency capability up to 1000 Hz?

A 0–1000 Hz frequency range allows this inverter to drive motors at very high speeds (for example spindle or high‐speed applications), but it requires that the motor and mechanical system are balanced for those speeds.

What does the “pollution degree 2” specification imply for contamination and maintenance?

Pollution degree 2 designates environments with non-conductive pollution, where occasional condensation or dust is expected but not continuous conductive buildup. Periodic cleaning, avoiding conductive dust accumulation, and controlling humidity are key for maintaining insulation integrity.

What mechanical installation constraints arise from its size (440 × 262 × 150 mm) and weight (≈12.74 kg)?

Its footprint and depth require rack or cabinet spaces that accommodate both the dimensions and airflow clearance; the depth especially may affect wiring routing and cable bend radius. The weight means secure mechanical mounting and vibration damping are necessary to avoid mechanical stresses or misalignment over time.
