Frequently Asked Questions

How does the resolver with integrated encoder provide absolute position detection over >4096 revolutions on MKD112C-024-KG0-AN?

A multiturn mechanism counts revolutions while the resolver supplies sine/cosine for commutation and fine angle. It reconstructs absolute position after power-up without homing to support tight servo loops in multi-axis machines.

How does the 192 mm flange and output-connector orientation aid drop-in replacements of Diax04/EcoDrive installations using MKD112C-024-KG0-AN?

The 192 mm face pattern preserves mechanical datum and coupling geometry. Its plug-in power/feedback cabling simplifies routing for easing retrofit without bracket or harness rework.

Why is a voltage constant KE = 0.545 V·min⁻¹ material when pairing MKD112C-024-KG0-AN with a drive and DC bus?

The back-EMF rises with speed (E ≈ KE·n) to ensure margin between generated EMF and DC-bus limit under field-weakening. It determines maximum speed under load and the regenerative handling requirements during decel.

What inertia-matching practices apply when the specified rotor/load inertia for MKD112C-024-KG0-AN is on the order of 0.024 kg·m²?

The targeted total load-to-motor inertia ratios is near 1:1–5:1 for responsive bandwidth. It employs compliant couplings and torsional analysis to avoid resonances. Tuning the notch/observer filters is required after mechanical integration to stabilize high-gain loops.

What environmental/thermal classes apply, and how do they shape cabinet cooling and sealing strategy?

The MKD112C series lists IP65 and insulation class F that indicates dust-tight/water-jet protection with 155 °C thermal class. It needs airflow or sealed cabinet conditioning to maintain ambient temperature within the 0–40 °C operating band.
