ACC-8DCE Delta Tau PMAC I/O Interface Board

The OMRON / Delta Tau PMAC Axes Breakout Boards have the connections typically made to a terminal block that is attached to the JMACH connector by a flat cable. The pinout numbers on the terminal block are the same as those on the JMACH connector for PMAC PC. While the numbering scheme for the pins on machine connectors on PMAC VME is different from that for PMAC PC, the physical arrangement is the same.

PMAC Accessory 8D (ACC-8D) (P/N 602205-100) provides a convenient means for routing PMAC's JMACH connector signals and power supply lines to a terminal block. In addition, ACC-8D provides the ability to connect several specific input/output options to PMAC conveniently through flat cables. These options include resolver interfaces, stepper motors converters and encoder isolator boards. If these options are not needed, use the ACC-8P terminal block board, which provides only the connection terminals. One ACC-8D provides all of the pinouts from a single JMACH connector on PMAC, which consists of four I/O channels (analog outputs, encoder feedback, and associated flags). The base version of PMAC has only one JMACH connector; therefore, it only needs one ACC-8D. A PMAC with Option-1 (additional four channels) has two JMACH connectors; therefore, it requires two ACC-8Ds. If a 4- channel ACC-24 (axis expansion board) is also used, there is one more JMACH connector; therefore, three ACC-8Ds are required. An 8-channel ACC-24 has two JMACH connectors; therefore, a total of four ACC-8Ds would be required. The ACC-8D OPT-5 provides the rail mount support for the ACC-8D.

PMAC's ACC-8DCE (ACC-8DCE) (P/N 3A0-602654-10X) is a CE Certified printed circuit for routing PMAC's JMACH connector signals and power supply lines to terminal block or D-Sub connectors. This accessory facilitates PMAC's connection to amplifiers and feedback signals, and provides a convenient means to connect several input/output options to PMAC. The ACC-8DCE design takes EMI considerations into account. The product optimizes performance by providing easy, efficient and cost-effective interface connections between the PMAC and amplifier connectors. The printed circuit board itself is layered by ground and power plains, with higher frequency lines imbedded in the middle layers.
