Connect the encoder cable with proper shielding and grounding
-
Provide adequate cooling; do not exceed the rated ambient temperature and current
Usage Notes:
-
As the model is discontinued, verify spare-part authenticity when sourcing replacements
-
Avoid overloading beyond 1.8 N·m rated torque or 22 A rated current to prevent demagnetization or winding damage
-
Periodically check bearing condition and encoder signal integrity
-
When commissioning, follow Kollmorgen’s tuning procedure to set gain parameters appropriate to the load inertia
