Axial and radial misalignment must be kept within tight bounds (typically a few 0.01 mm) to avoid bearing loads and vibration—use precision coupling or flexible spider couplings. Also, ensure shaft runout is minimised to preserve encoder accuracy and life of connected components.

The brake must be electrically released before motion and engaged only after the motor is fully stationary; failure to do so can cause excessive torque on the drive or mechanical stress. The brake adds inertia and must be considered when sizing deceleration ramps to avoid skidding or overshoot.

The motor can deliver peak torque only in short bursts (e.g., during acceleration), but sustained operation near peak will heat the windings. The continuous rating of 57 Nm (at standstill) gives a guideline—long periods above that require cooling margins or reduced duty cycles.

Long power and encoder cables may pick up noise; use shielded twisted pairs and keep cable impedance low to avoid voltage drop and feedback errors. Also, follow Rexroth’s recommended cable lengths and filters to maintain signal integrity, especially over distances beyond a few tens of meters.

That nominal speed forms the basis for dimensioning gearboxes and transmission ratios; if your load demands higher speed, you’ll lose torque margin. Conversely, for low-speed high-torque loads, gear reduction must not push the motor into mechanical resonance or overheating zones.
