Optional axis position information returns to the motion processor through the I/O chip, in the
form of encoder feedback, or through the CP chip, in the form of parallel-word feedback. This
position feedback may be used to detect motor stalling errors.
2.5 Peripheral device address mapping
Device addresses on the CP chip’s data bus are memory-mapped to the following locations:
Address
0200h
0800h
1000h
2000h
4000h
8000h
Device
Serial port data
Parallel-word encoder
User-defined
RAM page pointer
Reserved
I/O chip
Description

parity, stop bits, etc) for the asynchronous serial port
Base address for parallel-word feedback devices
Base address for user-defined I/O devices
Page pointer to external memory
Reserved for future use
