If you operate an injection molding machine, you know that Sepro robots are the backbone of high-throughput production. They are tough, fast, and reliable. However, like any high-performance servo-driven machine, they can run into thermal issues.
When a Sepro robot is down, the situation is "hot" for production. The manuals provide systematic troubleshooting steps:
Specific error codes and diagnostics to minimize downtime [2]. Key Sections to Focus On in the Sepro Manual
Each Sepro servo motor contains a (Positive Temperature Coefficient) wired directly to the drive. A failed thermistor can falsely trigger "HOT." sepro robot user manual hot
The internal thermal sensors (thermistors) inside the X, Y, or Z-axis servo motors have detected temperatures exceeding safe operating limits (usually above 85°C to 100°C).
Note the part numbers listed on the silver sticker of the overheating motor.
Organize your code into standard subroutines like PART GRIP IN MOULD or PART RELEASE ON BELT . If you operate an injection molding machine, you
For model-specific information, your best resource is the official user manual. You can often find them online:
Sepro Group is a global leader in automation for the plastics industry. Consequently, their user manuals are comprehensive technical documents designed to ensure operator safety, machine longevity, and process efficiency. This report highlights the critical sections of the manual, safety interlocks, and maintenance schedules required when operating Sepro robots in high-temperature environments.
If you have the physical binder or the USB drive that came with the robot, open the chapter (usually Chapter 7 or 8). When a Sepro robot is down, the situation
With the robot safely powered down and the mechanical brakes manually or pneumatically released (ensure the vertical axis is securely supported so it doesn’t drop!), try to move the axis by hand. It should move smoothly. If you feel catching, grinding, or immense resistance, you have a mechanical bind that is overloading your motor. Step 4: Clean and Inspect Cabinet Ventilation
| Error Code | Meaning | Immediate Action | |------------|---------|------------------| | | Axis 1 motor overtemp | Stop cycle, inspect cooling fan | | AL-203 | Drive amp overtemperature | Check cabinet exhaust filter | | AL-415 | Brake resistor overload | Reduce cycle speed or payload | | HOT-01 | General thermal shutdown | Manual reset required |
