Frequently Asked Questions
What are the practical benefits of an integrated absolute encoder with resolver feedback in CNC or robotics axes?
You get position at power-up without homing plus resolver robustness against electrical noise and vibration; the pair supports tight velocity and position loops. This combo is documented for MDD motors as “resolver feedback with integrated impulse absolute encoder.
What installation detail matters most with the 40 mm centering diameter and keyway shaft when coupling to ball-screw or timing-pulley loads?
Use the pilot (centering) fit as the primary alignment feature and match the key to DIN-6885 dimensions to avoid runout and fretting. MDD series documentation and parts listings call out the DIN-6885 keyway standard.
The motor has “without shaft seal”; when is that acceptable on food/packaging machines with washdown?
Use this variant only in dry, clean zones or add external guarding; for splash/dust exposure, select an MDD option with a shaft seal or provide environmental shielding. Optioned shaft-seal variants are referenced across MDD listings.
Any commissioning caveats when using resolver/absolute feedback on legacy versus newer Bosch Rexroth drives?
Legacy DDC/DKS and later DKC/IndraDrive controllers support resolver-based closed-loop operation; ensure feedback wiring and parameter sets match the specific encoder option. Controller manuals and drive comparisons note compatibility with MDD motors
What B2B benefits does this motor class offer for multi-axis packaging and small CNC retrofit projects?
Standardized MDD options (brake, encoder, connector orientation) and documented accessories shorten retrofit time and reduce commissioning risk. The project-planning guide explicitly covers mechanical/electrical integration and available options.
