While many causes of a "hot" alarm can be resolved with basic inspection and cleaning, certain situations require the expertise of a qualified technician. You should contact a professional if:
Thirdly, and perhaps most critically in the injection molding industry, the "hot" warning is associated with the end-of-arm tooling (EOAT) and the mold interface. Sepro robots are frequently tasked with removing parts from molds that are heated to extreme temperatures to ensure proper plastic flow. The user manual contains specific warnings regarding heat soak—the transfer of thermal energy from the hot mold to the robot’s wrist and arm. If the robot remains in the mold for too long, or if the EOAT is not properly insulated, the heat can damage sensitive proximity switches or deform the structural components of the arm. The manual provides critical data on dwell times and insulation materials necessary to mitigate this thermal risk. Disclaimer: Always refer to your specific model’s original

Ensure the tool weight (EOAT) and part weight entered into the Sepro software match the actual physical weight. Incorrect payload parameters cause the servo tuning algorithms to overshoot, overheating the motor. Preventative Maintenance Checklists
Remove and clean the intake air filters. Clogged filters are the number one cause of drive module overheating.
Do not guess which component is hot. Look at the active alarms on your Visual pendant. Note whether it specifies a particular axis (e.g., "Axis 1 Thermal Fault") or an internal drive temperature. Step 2: Perform a Safe Physical Inspection
Inspect pneumatic lines, electric drawings, and mechanical rails for wear. Error Messages:
