3.4.4 PROFIBUS DP, SK CU4-PBR
Up to four connected frequency inverters can be managed by the internal PROFIBUS DP module (control,
status messages, parameterisation and diagnosis).
• Baud rate: max. 12 MBaud
• Protocol: DPV 0 and DPV 1
• 2x digital inputs
• Automatic detection: PPO type, baud rate
• DIP switches for: addressing, bus termination
• Status LEDs: Module status, module error, bus
status, bus error, Dig. In 1, Dig. In 2
The terminal block of the Customer Unit SK CU4-PBR… is divided into two potential levels.
Up to 2 sensors can be connected via the terminal block (terminals C1 and C2).
NOTE
Looping of the 24V supply voltage (terminals 40/44) is in principle possible, however, a
maximum current load of
2A for the SK CU4-PBR must not be exceeded!
Detailed information about operation via PROFIBUS DP can be found in the relevant supplementary manual
