1320/1330 ELECTRICAL INTERFACE
Electrical interface between the Micropolis 1320/1330 drive and the host system is accomplished via five connectors as shown in the figure below.
Control Signal Connector J1 is a 34-pin board edge connector on the Device Electronics board. The signals on this connector control the drive and transfer drive status to the host controller.
Data Transfer Connector J2 is a 20-pin board-edge connector on the Device Electronics board. The signals on this connector contain read or write data.
DC Power Connector J3 is a 4-pin connector on the Motor Control board. It is used to supply +5V and +12V to the drive.
Ground Connectors J4 and J5 are 3/16-inch spade lugs located on the HDA and frame, respectively, and are used for grounding purposes. System characteristics determine proper ground connection.
