AVG Automation has continuously set the standard for speed,
precision, reliability, and product features in the resolver
decoder and programmable limit switch (PLS) marketplaces.
In the past, to implement such functions, the user purchased a
stand-alone Resolver Decoder or PLS, and connected it to the
machine. With the advent of the programmable logic con-
troller (PLC), users now want to integrate such functionality
with their PLCs.
Also, users don't want to tie-up their PLC's CPU with the
necessity of performing all the data processing, calculation, sig-
nal conditioning, and scaling of a resolver's input in order to
implement motion control actions.
Now, users of Allen-Bradley 1771 I/O, GE Fanuc 9070
VMEbus, and Siemens TI-505 PLCs can simply plug such
functionality directly into their PLCs—forever freeing the
PLC's CPU to perform other control functions.
RESOLVER DECODER FUNCTION MODULE
The M8350-010 Resolver Decoder Module is an intelligent
I/O module used with PLCs. All the parameters contained
within the Resolver Decoder can be accessed or programmed
through a series of commands. These commands can be easily
implemented by users in Relay Ladder Logic.
The M8350 Resolver Decoder communicates with the PLC
through INPUT and OUTPUT registers. To read information
from the M8350, or to write information to the M8350, the
PLC issues a command by writing to output registers. If a
response is required, it is read from the input registers.
Features include:
❐ Self-Monitoring Diagnostics with Fault Output
❐ Broken resolver wire detection
❐ Hardware-based microprocessor monitoring
❐ Simultaneous display of RPM and Position data
❐ Position and output status available to backplane every 700 µs
❐ Programmable motion detector (under-/over-speed switch)
❐ Fully absolute position; no loss of position under
any condition
❐ Programmable resolution; 20-4096 counts-per-turn
❐ Uses input from single-turn resolver
