Appendix B – Drive-to-drive link
432
The following diagram shows the wiring of the drive-to-drive link.
Datasets
Drive-to-drive communication uses DDCS (Distributed Drives Communication
System) messages and dataset tables for data transfer. Each drive has a dataset
table of 256 datasets, numbered 0…255. Each dataset contains 48 data bits.
By default, datasets 0…15 and 200…255 are reserved for the drive firmware;
datasets 16…199 are available for the user application program.
The contents of the two firmware communication datasets can be configured freely
with pointer parameters and/or application programming with the DriveSPC tool. The
16-bit control word and 32-bit drive-to-drive reference 1 are transmitted from one
dataset on a 500-microsecond (by default) time level; drive-to-drive reference 2 (32
bits) is transmitted from the other dataset on a 2-millisecond (by default) time level.
Depending on the drive control mode, the followers can be configured to use the
drive-to-drive commands and references with the following parameters:
