X1 connector
This connector may be used to connect the modules to each other through
the internal bus communicating the elements of the DDS system with each
other.
F. H3/58
X1 connector. Internal bus.
All the modules powered with the same power supply must be connected to
this bus and this condition is must to run it.
Together with each module, a connector and a ribbon cable are supplied for
this connection.
This bus must never be disconnected while the system is running.
X2 connector
8-pin connector of the modular drive.

F. H3/59
X2 connector. Control.
When the control circuit is supplied with 24 V DC (pins 7 and 8) the drive
runs an internal test.
If the module is ok, it closes the module status Drive OK contacts (pins 4 and
5). This contact stays closed while the modular drive is supplied with 24 V
DC and it runs properly.
To govern a motor, the drives also needs energy at the power bus.
The maximum internal consumption of the + 24 V DC supply input is 2 A (for
the bigger drives).
A 2.5 A fuse protects the internal circuits.
With the "Drive Enable" and "Speed Enable" inputs (pins 2 and 3) together
with the velocity command, it is possible to govern the motor. The
consumption of these control signals is between 4.5 and 7 mA.
