Frequently Asked Questions
What feedback architecture is used and why does it matter for commissioning?
It provides precise position and speed data with parameter storage for enabling fast drive setup and safe pairing of motor and controller. It reduces tuning time and ensures compatible cabling/limits per Rexroth guidelines.
How does the 60 Nm holding brake in MDD115D-N-015-R2L-130GA2 support vertical-axis safety?
The blocking brake secures loads during power-off or emergency stop for preventing drift on Z-axes or hoists. Its torque rating complements the motor’s continuous stall torque for stabilizing payloads during maintenance and e-stop sequences.
What cooling modes does MDD115D-N-015-R2L-130GA2 support, and when are they advantageous?
Its housing supports surface cooling and natural convection for enabling reliable operation without external blowers in many cabinets. It suits enclosed machinery and retrofits where airflow is constrained but thermal dissipation via frame is viable.
How does the 57 Nm continuous torque at standstill influence servo loop design? (MDD115D-N-015-R2L-130GA2)
Its stall torque enables tight position holding and smooth creep speeds without overheating under rated cooling. Its control engineers can apply higher proportional gains at low speed while maintaining thermal margins during dwell-heavy cycles.
Why is a 130 mm centering diameter relevant for mechanical alignment? (MDD115D-N-015-R2L-130GA2)
It improves coaxiality with gearboxes or belt drives for minimizing radial runout and vibration. Its better centering reduces bearing loads, enhances encoder integrity and helps maintain servo bandwidth at speed.

Internal Product Review
Bosch Rexroth Indramat designs the AC servo motor MDD115D-N-015-R2L-130GA2 with a plain shaft and integrated DSF encoder for feedback. It is accompanied by a 60 Nm holding brake and its pilot size is 130 mm. At 1500 min⁻¹ and 57 Nm standstill torque, it sustains torque at low speed. The unit's surface-cooled housing supports convection that makes it well-matched to systems like printing, packaging, textiles, robotics and machine tools.
