This manual introduces the technical details of the digital control board VT-HACD-DPC for hydraulic clamping units. The board includes recognized control technologies and advanced options for controlling hydraulic axes. The most notable feature is that the control system is bound to the machine's mechanical and hydraulic constraints.
The document provides a complete description of the VT-HACD-DPC 2X digital control board used for hydraulic clamping units. It details the board's features such as closed‑loop position control, force/pressure limiting, SSI or analog feedback, and advanced functions like active damping.
Installation, wiring diagrams, connector pin assignments, and front‑panel operation are explained, along with technical data, engineering notes, and recommended maintenance practices. The manual also lists required accessories, software (BODAC), and optional adapters for integration into hydraulic systems. This manual is written in Chinese.
