Frequently Asked Questions
How does the multiturn resolver/absolute feedback in MKD112C-058-KG3-AN reduce commissioning effort and position loss during power interruptions?
It maintains absolute position over >4096 revolutions to eliminate homing cycles after outages and preserving axis reference in complex multi-turn mechanics. It improves restart determinism and shortens recovery sequences on tightly coupled servo axes.
Why is the integrated 70 Nm holding brake relevant for vertical Z-axes or suspended loads on MKD112C-058-KG3-AN?
It provides static holding capacity when de-energized; release is by 24 VDC (±10%) to enable controlled disengagement during enable sequences. It reduces the need for external clamping and simplifies safe-state strategies on vertical axes.
What installation and mounting envelope constraints arise from the 112 frame size and 130 mm centering diameter?
Its frame size of 112 maps to a Ø130 mm pilot and large flange that eases alignment on IM B5/B05 face-mounts. Its geometry standardizes fit with heavy-duty gearheads and precision ball-screw housings in machine tools.
How does the Side-A power connector orientation in MKD112C-058-KG3-AN help cabinet routing and EMC?
The side-A orientation supports straight-through cable exits away from moving members to improve strain-relief and shielding continuity. Its pedictable connector orientation also reduces bend radii conflicts in multi-axis trays and minimizes cross-talk.
Is MKD112C-058-KG3-AN suitable for washdown or dusty environments, and what encoder considerations apply?
The IP-rated construction with shaft sealing and resolver-based feedback aids survivability against moisture and dust. Its resolver/absolute designs avoids fragile optics to enhance tolerance to contamination.
