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.
The field bus level is supplied with 24VDC from the system bus level via a DC/DC converter.
Up to 2 sensors can be connected via the terminal block (terminals C1 and C2).
NOTE
Looping of the 24V supply or GND is possible, however the maximum current load of 2A
must not be exceeded with theSK CU4-PBR!
Detailed information for operation via PROFIBUS DP can be found in the supplementary manual BU0220.
