3.1.3 Technical data
3.1.3.1 General data of the system bus network
Communication media DIN ISO 11898
Baud rate [kBit/s] • 50
• 125
• 250
• 500
• 1000
3.1.3.2 Feasible bus length
Depending on the data-transmission speed, the following bus lengths are possible:
Baud rate [kBit/s] 50 125 250 500 1000
Cable length [m] 1000 550 250 120 25
3.1.3.3 Communication times
The communication times for the system bus depend on
• the priority of the data
• the loading of the bus
• the data-transmission speed
• the processing time in the drive controller
Telegram throughput times
The telegram throughput time for 8 bytes of user data depends on the data-transmission speed:
Baud rate [kBit/s] 50 125 250 500 1000
Telegram throughput time
[msec]
2.7 1.05 0.52 0.26 0.13
Processing times in a LENZE controller
• Parameter: typically 30...50 msec
• Process data: 1...2 msec
