98 Communication protocol
The cyclic low priority communication service allows transmission
of up to 12 x 16-bit words with ACSM1 and ACS850 drives, and
10 x 16-bit words with ACS355 drives, in each direction. If a 32-bit
drive parameter is mapped to a PDO, it reserves two word spaces
in the cyclic low priority exchange. In ACS355 drives all
parameters are 16 bits long.
Example: With an ACSM1 or ACS850 drive, it is possible to map
four 16-bit drive parameters and four 32-bit drive parameters in
Rx/Tx PDOs.
