PRO-Series Controller Kit Installation Instructions
The PRO-Series single axis controller products which are available as stand-alone units are also
available in kit form
for
integration into the BRU-Series drive modules. In this cost effective
configuration, the PRO-Series controller card shares the BRU-Series power supplies, package, and
encoder.
Drawing 9097-1127 (BRU-500) and drawing 9097-1331 (BRU-200) provides installation instructions
for
mounting the PRO-Series controller card in the standard BRU-Series drives. The standard PRO-Series
Instruction Manuals should be used
for
operating instructions.
7.2 Spindle Orient and Auxiliary Function Card Installation Instructions
(BRU-500 Only)
The Electro-Craft Spindle Orient and Auxiliary Function Card mounts in the Electro-Craft BRU-500 to
provide basic auxiliary functions required
for
many spindle applications (refer to drawing
91
01-0236).
Figure
7-1
illustrates the Spindle Orient and Auxiliary Function Card operating with a BRU-500 in a
typical machine tool application to provide spindle orient
for
an
automatic tool changer plus additional
inputs and outputs used
for
spindle interface.

Figure 7·1 Spindle Orient and Auxiliary Function Application (BRU-500 Only)
The Spindle/Auxiliary Card accepts an analog velocity command input and differential encoder signal
feedback. The analog velocity command input and the forward and reverse inputs are used to generate a
velocity command for
the
spindle drive
to
fonow. The rate
of
change
of
this velocity command is limited
to
an acceleration/deceleration time which is user programmable. The Spindle/Auxiliary Card uses the
command and feedback information
to
provide outputs indicating zero speed, up-to-speed, and speed
below a programmable threshold. A pulse output is available for externally monitoring the speed
of
