Use the specified Ø130 j6 centering interface and follow torque and perpendicularity tolerances from the project planning manual to avoid preload or misalignment that can cause vibrations or bearing overload. Correct shim/bolting sequence and soft-mount options help maintain encoder accuracy and rotor balance under dynamic loads.

Confirm your drive supports the DSF protocol and mapping for commutation, speed and absolute position words, and ensure the connector pinout and cable length comply with Rexroth recommendations to avoid signal degradation. Also check stored motor parameter compatibility—many MDD motors include motor-specific parameters in encoder memory that the drive can read for automatic tuning.

Use the motor’s S1 (continuous) and Sx duty curves to compute RMS torque for your application cycle so the motor’s thermal limit isn’t exceeded; repeated high-current peaks reduce allowable continuous torque and require cooling or derating. For high duty cycles consider liquid cooling options or forced ventilation and verify ambient and mounting conditions against Rexroth planning data.

Record the exact Bosch Rexroth part number, connector orientation, motor length code, encoder variant (multiturn DSF) and centering diameter so replacements are electrically and mechanically drop-in compatible; also capture continuous and peak current limits for drive matching. Keeping the project planning manual and motor parameter file with the asset avoids mismatched firmware or incorrect tuning during swapouts.

Inspect seals and shaft coupling for wear monthly (or per duty), confirm connector seals and cable strain reliefs, and monitor bearing vibration and encoder diagnostics to detect early misalignment or contamination. Keep service records of torque cycles and ambient conditions to predict bearing and insulation replacement intervals instead of relying only on runtime hours.
