3.4.6 DeviceNet, SK CU4-DEV
Up to four connected frequency inverters can be managed by the internal DeviceNet module via DeviceNet
(control, status messages, parameterisation and diagnosis).
• Baud rate: Max. 500 kBaud
• Protocol: AC-Drive and NORD-AC
• 2x digital inputs
• DIP switches for: addressing, baud rate
• 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-DEV 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 45/46)or also (terminals 44/40) is in
principle possible, however, a maximum current load of
2A for the SK CU4-DEV must not
be exceeded!
Detailed information about operation via DeviceNet can be found in the relevant supplementary manual
