5.6.2 Piezo Driver Hub Mounting Options.
When the T-Cube piezo driver is used on the hub, together with the TSG001 strain
gauge unit, signals can be routed via dedicated internal communication channels.
These channels are selected via the piezo unit settings panel, or via the ‘MODE’
button on the top panel of the unit.
If Channel 1 is selected, the feedback signal runs through all the bays - see Fig. 5.10.
If Channel 2 is selected, the feedback signals run between adjacent pairs of T-Cube
bays (i.e. 1 and 2, 3 and 4, 5 and 6) - see Fig. 5.10.
Fig. 5.10 Hub Analog Input Channels
Only certain T-Cube arrangements allow the system to function correctly.
Furthermore, the setting for the
Analogue Input Source (EXT IN) parameter in the
piezo settings panel, depends on the bays in which the T-Cube units are fitted. The
various bay options, and their associated
Analogue Input Source (EXT IN) settings
are described in Fig. 5.11.
Caution
In general, when members of the T-Cube family are on the TCH002
controller hub, using the signal channels (Channel 1 and Channel 2),
users must ensure that:
The individual cubes are set up to use the intended signal channel.
Only one cube is driving the intended signal channel.
