Frequently Asked Questions
How does a multiturn absolute encoder change homing and recovery after power loss?
With DSF+MTG, the drive retains absolute position across power cycles (up to 4096 turns), minimizing re-homing. Relative DSF requires homing after power loss; absolute encoders may include battery monitoring in the drive.
Any coupling advice for the plain output shaft?
Use clamping sets/pressure sleeves for backlash-free, non-positive torque transmission preferred by Rexroth for MDD shafts. This avoids keyway play and preserves dynamic precision.
How should I handle vertical axes if the motor is supplied without a holding brake?
Choose a variant with a blocking brake or add an external load-holding device for fail-safe stops. Note that Rexroth specifies the holding brake is not a working brake and will wear if used dynamically.
Any housing/finish considerations for cleaning and environmental durability?
MDD housings are typically prime-coated (black RAL 9005) for chemical/weather resistance, but high-pressure steam cleaning can damage the finish. Ensure IP65 sealing (including shaft seal) for splash zones and avoid aggressive washdowns.
Is the Bosch Rexroth Indramat MDD090A-N-020-N2M-110GA0 housing suitable for dusty or wet areas?
Its standard MDD-series housing is typically IP65—dust-tight and protected against low-pressure water jets—but not for high-pressure washdowns; verify the exact variant on the nameplate. Shaft-seal configurations further improve ingress protection at the output.
