Frequently Asked Questions
How does MKD090B-047-KG1-KN behave at zero speed?
It supplies 12.0 Nm continuous torque at standstill to resist external forces. This capacity keeps the axis steady during inspections.
How precise is multi-turn tracking on MKD090B-047-KG1-KN?
Absolute detection over >4096 revolutions preserves count through interruptions. This feature minimizes re-referencing after resets.
What influences inertia planning on MKD090B-047-KG1-KN?
A rotor moment of inertia of 43 × 10⁻⁴ kg·m² defines acceleration behavior. That value guides tuning for snappy yet stable motion.
How does protection aid reliability on MKD090B-047-KG1-KN?
IP65 protection resists dust ingress and low-pressure jets. This sealing supports operation near coolants and debris.
What wiring aspect should be noted for MKD090B-047-KG1-KN?
Connection direction on Side B dictates cable routing and bend relief. This orientation helps clear guards and adjacent equipment.
