2.1.2 Customer units and extension units
To connect I/O control signals to the SK 700E frequency inverters, additional SK CU1-xxx IO
customer units are required. In contrast, the SK 5xxE series of frequency inverters by default comes
with respective onboard terminals to connect the standard I/O control signals.
When migrating to an SK 500E frequency inverter, you should provide for a performance level ≥
SK 511E with integrated onboard CAN / CANopen interface for SK 700E field bus customer units of
SK CU1-CAN and SK CU1-CAN-RJ types.
Information CAN / CANopen 24 V supply
When using the onboard CAN / CANopen interface of ≥ SK 511E frequency inverters, it is mandatory to connect
an additional 24 V power supply for the CAN / CANopen Bus to the RJ45 sockets.
For easier cabling and connection of functions (for 24 V supply and CAN / CANopen bus connection cables), the
WAGO adapter module RJ45/terminal (see chapter 2.1.3 Additional options for the functions) can be used with
conventional patch cables.
For the SK 5xxE series of frequency inverters, only one of the two PROFIBUS DP technology units
type SK TU3-
PBR or …-24V can be planned in connection with a SK 700E PROFIBUS DP field bus
customer unit type SK CU1-PBR.
Special extensions ENCODER / incremental encoder input type SK XU1-ENC and the POSICON
positioning control SK XU1-POS of the SK 700E frequency inverter are migrated to the SK 5xxE
series of frequency inverters with different performance levels such as the SK 52xE (with ENCODER /
incremental encoder input) or the SK 53xE (with POSICON / positioning control) series.
The sub-chapters to follow list some differences in function of the two series of frequency inverters
that must be heeded under all circumstances which must be taken into account when migrating from
the SK 700E to the SK 5xxE series or when migrating applications:
