Arburg ARB 709 Computer Board
 |
The Arburg ARB 709 is a control board used in high‑tonnage injection molding machines to manage motor drives, pressure regulation and safety interlocks. Common failures on this model include burnt or cracked power MOSFETs, degraded gate drivers for the servo motors, and failure of the 4 MB EEPROM due to thermal cycling; these faults often manifest as random resets or loss of motor control. Initial diagnostics should verify the main supply rails (±12 V, +5 V) with a multimeter, inspect the board for burn marks or cracked components, and check the status LEDs or error codes on the machine’s HMI for indications of drive or sensor faults.[oss-gpt-20b] |
