Frequently Asked Questions

How does the 3.18 Nm/A torque constant on MKD112C-024-KG3-BN influence current loop sizing and drive selection?

It defines torque per ampere that directly impacts commanded current, amplifier headroom and thermal utilization. Its correct Kt matching with Rexroth digital controllers keeps current loops linear and minimizes copper losses during continuous S1 operation.

What is the functional role of the 70 Nm holding brake on MKD112C-024-KG3-BN for vertical or indexing axes?

The electrically-released brake locks the shaft when de-energized for preventing gravitational creep or drift during e-stop and homing. It stabilizes position during power loss to enable safe fixturing and repeatable restart sequences.

Why use resolver-based absolute position detection (>4096 revs) on MKD112C-024-KG3-BN instead of an optical encoder?

The resolvers are tolerant to electrical noise, temperature swings and vibration, while the multiturn absolute memory removes homing cycles after outages. It shortens cycle time and improves startup repeatability in automated lines.

How do IP65 protection and a shaft seal benefit MKD112C-024-KG3-BN in packaging and printing environments?

They resist particulate and low-pressure washdown ingress for protecting bearings and feedback interfaces in ink, dust or moisture-laden zones. It supports uptime on conveyors, folders and form-fill-seal stations.

What retrofit advantages come from the MKD112 frame (192 mm flange) and Side-B connector orientation on MKD112C-024-KG3-BN?

The standardized flange envelope eases drop-in replacements across MKD112 variants. Its side-B power/feedback exits simplify cable routing away from guards to improve EMC and service access in tight cabinets.
