Toyokoki TNC-ACII Control Unit
 |
Toyokoki TNC‑ACII is a six‑axis CNC control unit used in press brakes and other heavy‑industry machines. Common failures on this model include power supply board faults (over‑voltage, capacitor burn‑out), I/O module degradation, and firmware corruption that can cause loss of motion or error codes such as “E‑01” or “E‑02”. First‑check diagnostics: verify the 24 V/48 V DC rail voltages with a multimeter; inspect all connectors for loose pins or corrosion; and review the controller’s diagnostic display for any stored fault codes. If the unit powers up but does not execute motion, test the servo drive outputs and confirm that all safety interlocks are cleared.[oss-gpt-20b] |
