6.17.5 PCD3.H31x, motion control module for servo-motors, 1-axis encoder
Application
The PCD3.H31x motion control module is an intelligent I/O module. The module is
used to position a single axis with variable speed control DC or AC servomotors.
This requires the drive unit to have a power stage and incremental shaft encoder
for capturing position or speed.
Each module contains a single-chip processor that independently controls every
movement according to parameters supplied by the user program (velocity,
acceleration and destination position). The axes are controlled independently of
each other, which means that no interpolation is possible to trace curved paths.
On the other hand, linking of multiple axes (point-point) in quasi-synchronous
operation cane be programmed.
This I/O module cannot currently be used with the PCD3 RIO head station
