Frequently Asked Questions
What applications are well-matched to the MDD115D-N-015-N2L-130PB1’s 57 Nm standstill torque and 1500 min⁻¹ rating?
These ratings suit indexed motion, synchronized webs and moderate-speed axes in packaging, printing, textile processes, and transfer/handling lines. Its high contouring precision and dynamic response are characteristic of MDD115/093 platforms.
How does Digital Servo Feedback (DSF) in MDD115D-N-015-N2L-130PB1 improve control accuracy and commissioning?
It provides fine-resolution position and speed data for enabling tighter loop gains and smoother low-speed motion without dithering. It also streamlines wiring and parameterization with Rexroth digital drives to reduce setup variability across machines.
Why is a 130 mm centering diameter specified, and how does it affect mechanical integration for MDD115D-N-015-N2L-130PB1?
The 130 mm pilot registers the motor to the machine interface for minimizing radial runout and misalignment at the flange. It improves coupling life that reduces bearing side-loads and simplifies repeatable alignment during service.
What role does the 45 Nm blocking brake play on MDD115D-N-015-N2L-130PB1 during power-off states?
The holding brake secures vertical or overhauling loads for preventing drift when drives are disabled. It also aids emergency stops by maintaining shaft position until the controller re-establishes torque control.
How does the keyway shaft and shaft seal combination benefit the MDD115D-N-015-N2L-130PB1 in industrial environments?
Its keyed interface provides positive torque transmission and repeatable phasing for pulleys or couplings. Its shaft seal mitigates ingress of dust and coolant mist for helping maintain grease integrity and encoder cleanliness over time.
