Frequently Asked Questions
How should the 48.0 Nm continuous stall and 180 Nm peak of MKD112D-027-KG0-BN be mapped to duty-cycle limits?
Its thermal modeling in the drive is important to ensure RMS torque and remain within the continuous region while allowing short-term overloads for acceleration. Its repetitive peaks must respect motor time constants and cooling assumptions to prevent cumulative heating.
Which drive-sizing considerations follow from the 40 A rated and 120 A peak current of MKD112D-027-KG0-BN?
The selection of an amplifier whose continuous/peak output envelopes exceed these currents with margin and whose DC-bus voltage matches the EMF constant of winding 027. Its cable ampacity, fusing and bus energy handling for regenerative events is also important.
How does the 130 mm centering (pilot) diameter of MKD112D-027-KG0-BN influence mechanical alignment and runout?
The pilot handles radial location for decoupling alignment from bolt clearance and improving concentricity. Its accurate pilot fits lower synchronous runout to reduce cogging-like ripple in velocity and improving contour fidelity on CNC axes.
How does “absolute (>4096 revs)” interact with the encoder’s multiturn gear and battery life on MKD112D-027-KG0-BN?
The multiturn mechanism counts revolutions mechanically/electronically and preserves count via a battery for maintaining absolute position after outages. Its plan periodic battery replacement (typ. multi-year) to avoid reversion to relative mode and forced re-homing.
What EMC and grounding practices apply to the terminal-box connection used by MKD112D-027-KG0-BN?
Its motor-and-feedback cable shields with 360-degree bonding at entry and provide a short for low-impedance PE connection to the machine ground. It keeps power and feedback routes segregated and minimizes loop areas to reduce common-mode emissions.
