Frequently Asked Questions
What feedback system does the MDD115D-N-020-N2L-180GA0 use, and why does it matter?
The motor employs digital servo feedback (DSF) that reports position and speed while storing motor parameters for enabling controller auto-recognition and safer commissioning. It improves loop tuning and repeatability across drive replacements or field service swaps.
How does the 57.0 Nm continuous standstill torque of MDD115D-N-020-N2L-180GA0 translate to applications?
The motor can hold/produce 57 Nm continuously without thermal overload, ideal for tensioning, indexing or vertical axes with constant load. Its characteristic benefits packaging formers, tool changers and feeder rollers needing steady torque.
Why is the plain, sealed shaft design advantageous in industrial environments?
The plain shaft with shaft seal simplifies coupling choices and minimizes ingress of contaminants for supporting IP-grade protection practices. It helps extend bearing life when paired with appropriate couplers and grounded mechanics in printing and textile lines.
How does the 2000 min⁻¹ nominal speed of MDD115D-N-020-N2L-180GA0 affect drive sizing?
Its base speed favors torque-dense axes with moderate speed ranges for letting designers choose gear ratios that keep the drive within current limits. It balance eases thermal management on continuous-duty stations.
What is the role of the 180 mm centering diameter on MDD115D-N-020-N2L-180GA0?
The Ø180 mm pilot locates the motor concentrically to the machine interface for reducing misalignment-induced vibration. Its accurate centering helps maintain encoder integrity and improves contouring quality in CNC and converting equipment.
