Frequently Asked Questions

What are the implications of the rated current being 100 A for system design when using the Bosch Rexroth Indramat HDS03.2-W100N-HT02-01-FW?

A 100 A rating demands sufficiently sized power wiring, fusing, and connectors to prevent voltage drop and overheating; thermal derating may apply if ambient temperature or enclosure ventilation is poor. Also, the DC bus supply and supply modules must support transient loads without drop-outs, especially under peak load or acceleration phases.

How does using SERCOS as the command communication interface affect synchronization and latency in multi-axis systems?

SERCOS provides a deterministic, real-time cyclic fieldbus which enables tight synchronization among axes; this reduces jitter and improves motion accuracy. However, cable length, network topology, and termination must be managed to avoid latency or signal integrity issues at high data rates.

What is the practical significance of the built-in internal air blower cooling method in an industrial cabinet?

The internal blower helps maintain consistent internal temperatures even under high load, but it requires regular maintenance (e.g. filter cleaning) and ensures that airflow paths are not blocked in the cabinet; otherwise hotspots will reduce reliability. Also, the blower noise and vibration may need dampening in sensitive installations.

What insulation class “C” means in terms of allowable ambient temperature and winding stress?

Insulation class C typically allows maximum winding or component temperatures up to ~200°C, giving more margin under high ambient or load stress; however, overall system limits (electronics, cooling) often restrict usable ambient to lower values (e.g. +45 °C). Degrading insulation from repeated temperature cycling can shorten service life if not carefully managed.

In what real-world applications would the DIAX04 HDS drive with these specs (100 A, blower cooled) be particularly advantageous?

It’s well suited for high torque or high inertia applications such as robotics, large pick/ place or gantry axes, or winding/ unwinding machines where large current surges are common. Also in packaging, converting, or paper processing where fast dynamic response and continuous heavy duty cycles are required.
