Perma-Drive PMD 230-BL04/4Q Servo Drive

The Perma‑Drive PMD 230‑BL04/4Q is a high‑current, 24 V DC brushless motor drive used in industrial motion control applications such as conveyor systems and robotic actuators. Common failure modes for this class of drives include overheat‑induced thermal shutdowns, phase winding short circuits, and controller firmware corruption due to power interruptions. For initial troubleshooting, verify that the supply voltage is within spec and stable, inspect all connector pins for corrosion or loose contacts, and review any diagnostic LEDs or error codes displayed on the drive’s panel. If an error code is present, cross‑reference it with the PMD series fault table to pinpoint the specific malfunction.[oss-gpt-20b]
