-IO Expansion Board Ndrive HPe 10/20/30
3.2.1. -DUALPSO and -TRIPLEPSO Laser Firing Options
The -TRIPLEPSO option is only available on the -IO option board.
The Ndrive HPe 10/20/30 allows two and three-axis laser firing via its -DUALPSO and -TRIPLEPSO
options. To accomplish this, the encoder signals from a second/third drive must be jumpered (or daisy-
chained) from that Ndrive HPe 10/20/30 to the drive with the -DUALPSO or -TRIPLEPSO options. This
requires an encoder signal from another axis via the J205 connector or via one of the two SSINet
connectors. If the SSINet is used it requires a cable (see
Table 3-11 and Figure 3-6 ) from J302 to J302 of
each HPe (J302 to J302 or J303 to J303 of the other Ndrive HPe 10/20/30, both connectors have two bi-
directional ports). Refer to the A3200 Help File for programming information.
Software controlled PSO pre-scalars may be used to limit the data rate of each encoder being tracked
without affecting the servo loop data rate.
See Section 3.2.1.1. for an example of two and three-axis firing. See the A3200 Help file for more information
on parameter configurations.
3.2.1.1. Multi-Axis Firing
In this example, the X axis has the -TRIPLEPSO option and the Y and Z axes represent the other two axes
that will be tracked. The Y and Z axes output their encoder feedback through SSINet ports 1 and 2,
respectively, to the X axis. The Z axis must have its SSINet port 1 configured as an output for its encoder
feedback signal, and the Y axis must have its SSINet port 2 configured as an output for its encoder feedback
signal. Since the Z axis does not use its SSINet port 2, it should be configured as an Input. Similarly, the Y
axis does not use its SSINet port 1 so it should also be configured as an Input. The X axis must have both
SSINet ports 1 and 2 configured as Inputs.
In general, if an axis has an SSINet port configured as an output, then that SSINet port must be configured
as an input on all other axes which it is connected to. Otherwise, encoder or marker data may be faulty.
