Pacific Scientific Pc2303-010 00296701 Brushless Servo Drive

The PC2303‑010 is a single‑axis, GcoderTM based brushless servo drive from Pacific Scientific (now part of Kollmorgen). Common failures on this model include power supply voltage drops or spikes that trigger the built‑in over‑voltage protection, loss of communication with the host controller due to degraded I/O pins, and overheating of the internal MOSFET array caused by prolonged high‑current operation. Typical symptoms are intermittent run‑time errors, “drive offline” status codes, or sudden shutdowns during load cycles. First‑check diagnostics: verify the 48 V DC supply is within spec and stable; inspect all I/O connectors for corrosion or loose contacts; review the drive’s fault log for error codes such as E01 (over‑voltage) or E02 (communication loss).[oss-gpt-20b]
