-IO Expansion Board
3.2.2. -DUALPSO and -TRIPLEPSO Laser Firing Options
-DUALPSO and –TRIPLEPSO options are only available on the -IO option board.
The Ensemble HPe 150/200 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 Ensemble HPe 150/200 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
each HPe (J302 to J302 or J303 to J303 of the other Ensemble HPe 150/200, both connectors have two bi-
directional ports). Refer to the Ensemble Help File for programming information.
Multi-axis PSO can track encoder signals with a maximum data rate of 8.33 MHz. Signals in excess of this
rate will cause a loss of PSO accuracy. 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
3.2.2.1.for an example of two and three-axis firing. See the Ensemble Help file for more
information on parameter configurations.
3.2.2.1. 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.
