The S1 encoder provides absolute angular position within one revolution through a Hiperface-compatible interface. The drive, feedback cable and controller parameters must be suitable for S1 feedback.
The keyed shaft provides positive torque transmission through a compatible keyed coupling. Key dimensions, hub fit, alignment and bearing loads must be checked. Brake code 0 confirms that no motor holding brake is installed.
Natural-convection cooling simplifies installation but requires adequate airflow and motor-flange heat transfer. Continuous output may be reduced by high ambient temperature, restricted airflow or an intensive duty cycle.
Typical uses include machine-tool axes, printing and converting machinery, packaging systems, metal-forming machinery, winding equipment and industrial handling systems. Final motor selection must consider load inertia, acceleration, gearbox ratio and thermal requirements.
