Frequently Asked Questions
What’s the correct supply and wiring for the holding brake?
Use a regulated 24 VDC ±10% brake supply with at least 0.75 mm² conductors. The brake is for holding at standstill, not as a service/emergency brake.
Does the shaft seal change performance or maintenance needs?
Shaft seals add friction and heat, so verify thermal limits at high speed and consider more frequent inspections for wear in dusty/oily environments. This aligns with general MDD planning guidance for sealed, high-speed applications.
How does the 10,000 min⁻¹ nominal speed influence gearbox and coupling selection?
Choose couplings/gearboxes rated above 10k rpm and check permissible input speed to avoid overheating and seal wear. High speed favors low-inertia couplings to preserve system bandwidth.
What IP protection should I expect and how does that impact routing?
MDD motors are commonly supplied with IP65-level protection at housing, shaft, and connectors; maintain cable gland sealing to preserve rating. Route power/feedback cables separately and bond shields at the drive end.
For Bosch Rexroth Indramat MDD025A-N-100-N2K-040GL1, what installation checks are most critical?
Confirm resolver/absolute encoder configuration in the drive, verify 24 VDC brake power, and validate rotation sense before coupling the load. This model is documented at 10,000 min⁻¹ with resolver plus integrated absolute encoder, so ensure the drive’s feedback and speed limits match.
