The Industrial Device Corporation 962‑30K is a dual‑axis motion control indexer that outputs step/direction or CW/CCW signals to servo or stepper drives and includes digital/analog I/O and an integrated AC power supply. Common failure points for this model are the front‑panel keypad, RS‑232C communication interface, and the internal motor driver boards; overheating of the motor drivers and loose wiring in the power connector are frequent causes of intermittent operation. Begin troubleshooting by verifying 120 VAC input voltage and ensuring the unit’s internal fuse or circuit breaker is intact, then check the RS‑232C serial link for correct baud rate and cable integrity, followed by inspecting the keypad and driver board for visible damage or burnt components.[oss-gpt-20b]
