What cooling requirements should be met to ensure reliable thermal performance of the HMS01.1N-W0350-A-07-NNNN (Bosch Rexroth)?

To maintain safe junction temperatures, adequate airflow through the internal blower is needed and ambient temperature must remain within 0-40 °C; high duty cycles or reduced cooling airflow will require de-rating the current

What is the difference between constant current capability versus peak or rated maximum current in this inverter?

Although the driver can reach a maximum current of 350 A, its continuous (or “constant”) current rating is lower (≈ 250 A) to avoid thermal stress, so for sustained operation design for the continuous current limit.

What control voltage supply is required, and what are the implications of the unit not having an internal power supply?

The control and logic circuits require 24 V, but since the unit is “not equipped” with internal power supply, you’ll need an external 24 V source with enough capacity; failure or instability there can cause control malfunctions or loss of safety interlocks.

What safety grounding and wiring cross-section should be used with this inverter to satisfy UL / EMC and safety standards?

Motor connections and grounding must follow specified copper cross-section wire (material: Cu, conductor temp rating 60/75 °C), with proper grounding of the frame, ground straps, and EMC shielded cable to meet the EMC / UL specifications in the manual.

How much power dissipation (losses) should one budget for continuous operation at the rated constant current?

At continuous current and with nominal DC bus usage, power dissipation can reach up to ~2750 W based on UL specs for this power class, meaning substantial cooling and heat sink/enclosure design must be accounted for.
