A plain shaft often implies a smooth cylindrical interface, sometimes with shrink fit or clamping coupling designs; keyways may not be present, so coupling must accommodate friction or clamping torque without slippage. You must check whether your coupling design can reliably transmit torque under dynamic load without a key.

Low inertia and high encoder resolution allow tight velocity and position loops for coordinated moves, but you must size drive current reserve for transient accelerations. Cable routing, EMC shielding, and drive tuning (e.g. decoupling cross-axis resonance) are critical in multi-axis systems.

Operating near standstill torque causes high I²R losses and local heating; thermal design (cooling, heat sinking, ambient conditions) becomes crucial to avoid winding insulation stress. The drive/feedback must monitor temperature sensors integrated into the motor (as per MDD series documentation) to prevent overheating

Because of the multiturn absolute encoder, the motor/drive retains the absolute rotor position across power cycles (no rehoming). This enables faster restarts and zero referencing without external encoders or resync routines.

The quality and resolution of the integrated multiturn absolute encoder (DSF) and the current control bandwidth set the maximum reliable speed before angular error grows significantly. At high rpm the feedback latency and rotor inertia may dominate the control error.
