CAN Communication
The DYN4-
□□□
C2-00 servo drive models are compatible with CAN 2.0A specification. The data frame format is
a proprietary DYN servo drive format with efficient data packaging and high transmission rates up to 1Mbit/s for
fastest cycle time.
Please refer to the CAN communication manual for detailed specificaitons.
