Cyclic transmission
[Motion mode]
Communicates data cyclically between stations using PDOs.
• Maximum RPDO size: 80 bytes/axis
• Maximum TPDO size: 80 bytes/axis
• The servo amplifiers support variable PDO mapping.
Transient transmission
[Motion mode]
Communicates data non-cyclically between stations using
SLMP and other protocols. SDOs can be used to read and
write objects of the servo amplifier.
