Frequently Asked Questions
How is the 45.0 Nm holding brake on MDD115D-N-020-N2L-130GB1 used in vertical axes or safety stops?
The brake maintains axis position when drives are disabled for preventing gravity-induced drift on Z-axes and enabling secure maintenance states. It’s specified for static holding not dynamic braking during emergency deceleration.
How does the continuous standstill torque of 57.0 Nm on MDD115D-N-020-N2L-130GB1 affect low-speed contouring?
It permits sustained force at zero/near-zero speed for holding, tensioning or creep feeds without overheating within thermal limits. It is crucial for grinding, forming or precision dwell operations requiring steady torque at minimal speed.
What is the role of the 130 mm centering diameter in MDD115D-N-020-N2L-130GB1 mechanical integration?
The pilot registers the motor concentrically to the gearbox or machine plate for minimizing runout and coupling misalignment. Its standardized centering simplifies drop-in replacement within MDD 115-frame installations across diverse machines.
How should cabling be routed for the side-B connector orientation on MDD115D-N-020-N2L-130GB1?
The side-B orientation facilitates rear/axial cable exits in compact enclosures for reducing bend stress. It is important to use Rexroth-specified feedback/power cables to maintain signal integrity for DSF encoders and comply with approved motor–drive combinations.
For MDD115D-N-020-N2L-130GB1, what are the implications of a 90-minute thermal time constant during duty-cycle planning?
Its long thermal constant means temperature rises slowly, while transient overloads (e.g., to 177.2 Nm) are thermally buffered. Its duty cycles should still honor steady-state limits and cooling assumptions to avoid cumulative heating.
