SK 200E Manual for frequency inverters
92 Subject to technical alterations BU 0200 GB-4411
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.
The field bus level is electrically isolated from the system bus level and must therefore be separately sup-
plied with 24VDC.
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-DEV!
Detailed information for operation via DeviceNet can be found in the relevant supplementary manual BU0280.
