Frequently Asked Questions
How does the resolver with integrated multiturn absolute encoder in MKD112D-027-KG3-AN reduce commissioning time and improve index recovery after power loss?
It preserves absolute shaft position across 4096 turns to enable immediate motion without homing and faster recovery after interruptions. Its resolver feedback also withstands electrical noise and thermal drift typical of industrial environments.
What does a 1.2 Nm/A torque constant imply for drive current sizing on MKD112D-027-KG3-AN?
The required motor current scales directly with demanded torque; e.g., 55 Nm peak needs ≈46 A (55 / 1.2) excluding dynamic effects. Select a controller with current headroom for acceleration, cogging compensation, and field-weakening margins.
Is the 70 Nm holding brake on MKD112D-027-KG3-AN sufficient for vertical (Z-axis) retention without drift?
It’s engineered for static holding, its adequacy depends on reflected load torque (mass×g×radius / gear ratio). Its safety factors and brake datasheet values are important to notice before relying on it for emergency stops.
What does IP65 with a shaft seal practically enable on MKD112D-027-KG3-AN, and what are limits in washdown lines?
The IP65 rating resists dust ingress and water jets, its shaft seal further curbs contamination at the journal. Its caustic washdowns or high-pressure spray add guarding.
What is its inertia value and its importance?
Its specified inertia value is 8.3 kgcm². It indicates controlled performance in rapid acceleration and deacceleration.
