Communication Parameters for VFD-C2000 Connected to PROFIBUS DP
When VFD-C2000 is connected to PROFIBUS DP, please set up the communication parameters for it
according to Table 4.1-1.The PROFIBUS DP master is only able to read/write the parameters of VFD-C2000
after the communication parameters are set.

Note: The value of 09-70 is the address of VFD-C2000 on the PROFIBUS DP network. The address
has to be consistent with the address of VFD-C2000 during configuration. Changing the value in 09-70
when VFD-C2000 is working will be invalid. After the value in 09-70 is changed, shut down VFD-C2000
and re-power it to make the parameter valid.

Transmission Distance and Baud Rate
The baud rate range for PROFIBUS DP is 9.6kbps ~ 12Mbps, and the length of transmission cable varies
upon the transmission speed. The transmission distance ranges from 100m to 1,200m. SeeTable 4.2-1 for
the baud rates CMC-PD01 supports and their corresponding communication distances.

Applicable Data Form for CMC-PD01 and Introduction to PKW, PZD
4.3.1 Applicable Data Form for CMC-PD01
The data form defined by PROFIDrive can be used for cyclic data exchange. These defined data form is
called "Parameter Process data Object" (PPO). Apart from PPO, the cyclical data can be configured as
EXT CONF1 or EXT CONF2. Based on different demands, the two extended configurations are able to
achieve 4 process data words. See Table 4.3-1 for the data forms CMC-PD01 supports.
