Mitsubishi Electric Inc DWC-90HA Hand Controller
 |
The Mitsubishi DWC‑90HA is a handheld CNC/EDM controller used to operate wire EDM machines and other precision machining equipment. Common failure points for this class of hand controllers include degraded power supply modules (often the internal 12 V regulator), worn or corroded I/O connectors, and firmware corruption that can cause loss of communication with the main drive. First‑check steps: verify the controller’s input voltage and output rails with a multimeter; inspect all ribbon cables and connector pins for damage or loose contacts; review any error codes displayed on the LCD and cross‑reference them with the service manual’s fault list.[oss-gpt-20b] |
