Frequently Asked Questions

What trade-offs occur when using higher switching frequencies (e.g. 8 kHz) with this type of drive?

Higher switching frequencies reduce motor ripple and improve response but increase switching losses, reducing the continuous current capability (from ~50 A at 4 kHz down to ~35 A at 8 kHz). They also generate more heat in the drive, stressing both cooling systems and power electronics.

How is the SERCOS communication interface beneficial in multi-axis systems using this controller?

SERCOS offers deterministic real-time communication, low latency, and precise synchronization across axes, which improves performance in robotics, machining, or coordinated motion. It also simplifies wiring and control topology when multiple drives need synchronized motion or feedback

What special considerations arise when deploying the Bosch Rexroth Indramat HDS03.2-W100N-HT12-01-FW in B2B industrial automation?

Matching the controller with properly rated supply modules, motor types (MKD, MHD, 1MB, 2AD), and feedback systems is essential to avoid oscillations or poor performance. Lifecycle support (spares, firmware, diagnostics over SERCOS, and service documentation) should be part of procurement, especially because these are legacy/obsolescent product lines.

What distinguishes function ID Code 12 in the DIAX04-family drive controllers?

Function ID codes define certain firmware or functional configurations (e.g. parameter sets, safe-guarded functions, signal modules) in the DIAX04 system. Using a different Function ID Code may require re-programming or different command/diagnostic behavior and may affect compatibility of replacement units or spares

What additional hardware (accessories) might be needed for safe regenerative braking or frequent stops?

If the machine generates energy when braking and the supply module (HVE/HVR) cannot absorb it, an external brake resistor (e.g. HZB series) is recommended. Also consider capacitor modules (HZK) if start-stop cycles are frequent to buffer power demand
