The plain shaft with seal helps protect internal bearings and windings from dust or contaminants (especially in packaging or forming machines). Still, one should inspect the seal periodically and avoid side-loads that might degrade the seal or shaft surface over time.

Above the nominal speed, available torque begins to drop due to back-EMF and current limits in the amplifier. So for rapid motion profiles, the controller must be tuned to account for torque roll-off at high RPM.

In systems requiring high-precision contouring—like machine tools, robotic axes, or packaging gantries—the integrated DSF enables low-latency commutation and direct encoder feedback, reducing servo lag and improving path fidelity. This reduces the need for external encoders or wiring, simplifying system architecture.

Ensure the variant (e.g. “GB2”) matches the encoder, braking, and cooling options required, since minor suffix changes can imply different encoder protocols or finishes. Also verify the thermal class and insulation rating to match your ambient and duty-cycle constraints.

Because the encoder retains absolute position over power cycles, the drive can immediately resume closed-loop control without a reference move. This reduces downtime in B2B systems that require fast restart cycles.
