Product Description
Is your legacy Allen-Bradley Bulletin 1331 AC drive failing? Finding support for older drives can be challenging. ROC Industrial offers specialized repair services for the Allen-Bradley 1331 series, helping you extend the life of your existing equipment and avoid costly upgrades.
Is Your Device Showing These Signs?
Allen Bradley Bulletin 1331 AC drives commonly experience failures related to electrolytic capacitor degradation within the DC bus, leading to over-voltage faults and drive trips. IGBT failures are frequent due to thermal stress or excessive load demands, necessitating replacement. Encoder feedback issues cause erratic motor control, requiring encoder repair or replacement. Power supply malfunctions result in complete drive failure, demanding power supply component level repair. Communication errors on the serial communication ports, such as RS-485, disrupt network connectivity, often fixed by replacing the communication module.
Technical specifications
The Allen-Bradley Bulletin 1331 AC Drive is a microprocessor-controlled PWM drive from a previous generation. Repairing these legacy drives involves diagnosing faults in their power sections (SCRs/transistors, capacitors), control logic boards, and analog interface circuits. ROC Industrial has experience in troubleshooting and performing component-level repairs on Bulletin 1331 drives to address common failure modes and restore operation.
