Features: 7× higher inertia than B-series equivalent, smooth mid-band response, robust IP65 construction.
Applications: Printing presses, converting machinery, injection molding, assembly stations.
Construction: Cast aluminum end-bells, stacked lamination stator, rare-earth rotor, double-bearing shaft.
Installation: Flange-mounted; align coupling to avoid radial preload; use resolver cable with continuous shield.
Precautions: Class H allows high temp but PTC trip set lower—do not disable thermal input on drive; verify A9 suffix wiring against original drawing before energizing.
