This section lists the signal names (at the connector pins) and the Motion Block FPGA functions associated with each.

XCVR Functions

The XCVR signals are used for many different functions. The XMP-PCI and XMP-CPCI each offer three XCVRs (A,B,C) per motor, while the XMP-CPCI-3U offers six XCVRs (A,B,C,D,E,F) per motor. The various XMP boards and XCVR combinations are listed in (See XCVRs for various XMP products below).

1. On non-standard XMP-CPCI-3U controller, Axis 2 XCVR D is not connected to rear I/O, giving a total of 23 XCVRs. Standard -3U controller has 12 XCVRs.

These multi-purpose XCVR signals may be configured for several different input or output functions. The available XCVR functions for one motor are detailed below; the XCVRs for all other motors are the same.

Note

an option to invert any output function is also available.

User I/O

There is one USER I/O signal associated with each motor (4 per motion block, 8 for an 8-axis board, 16 for a 16-axis system). These general purpose, opto-isolated signals may be used as either an input or an output. Selecting between input or output is done via the electrical polarity of the external circuit: the polarity of an input circuit disables the output (the output transistor cannot turn on with Vcollector < Vemitter), while the reverse polarity enables the output and disables the input (due to a blocking diode). The circuit design guarantees all components remain within operating limits through the full range of possible values (i.e., with Vin = 24 V, both input and output parts are within spec).
