1.6 THEORY OF OPERATION
Drawing D-93030 shows a system overview.
•
MICROPROCESSOR SYSTEM
The BDS5 is a digital positioner and servo drive
combined into one unit. The velocity loop is 100%
digital. The BDS5 has battery backup RAM to
remember your program and most variables through
power-down.
•
RESOLVER-TO-DIGITAL CONVERTER
The BDS5 is based on a Resolver-to-Digital (R/D)
converter. The R/D generates a tachometer signal for
your convenience. However, the BDS5 does not use
the analog tach signal.
•
SERIAL PORT
The BDS5 has a serial port for communications. This
port allows you to monitor the operation, issue
commands, and transmit a program.
•
DISCRETE INPUTS
The BDS5 has 23 discrete inputs, including REMOTE
ENABLE which is on Connector C2 only. Note that
two signals, HOME and CYCLE, can be input to the
BDS5 on two connectors, C2 and C7. Connector C2
provides these three signals with optical isolation.
Connector C7 expects non-isolated TTL signals on a
26-pin ribbon cable connector. Optional Connector
C8 expects non-isolated TTL signals on a 50-pin
ribbon cable connector.
•
DISCRETE OUTPUTS
The BDS5 has 10 discrete outputs. Notice that O1
appears both on Connector C2 with optical isolation
and on Connector C8.
•
ENCODER INPUT
The BDS5 accepts external inputs in encoder format.
This can come from a master motor in a master/slave
system. Note that you must use a resolver, even if you
use a feedback encoder with the BDS5.
