Nord Drivesystems SK 750E-751-323-A - Optional Equipment; Bus-Type Customer Interfaces (SK CU1-CAN-RJ, SK CU1-PBR)

3.3 Overview of the customer interfaces

3.3.7 Bus-type customer interfaces, SK CU1-CAN-RJ, SK CU1-PBR
(SK CU1-CAN-RJ, part no.: 278200052)
(SK CU1-PBR, part no..: 278200030)
All bus-type customer interfaces are equipped not only with
data ports, but also with conventional digital inputs and out-
puts.
Moreover a relay contact is provided which can be used to
transmit brake control information or a warning to any other
connected system. The digital input is provided with a switch-
ing threshold of 2.5V to enable evaluation of the temperature
sensor. Alternatively this input may also be correlated with an
emergency stop function.
The same features are always provided on all of the bus ac-
cess subassemblies, with the exception of the Profibus op-
tion where the X6.3.83 connector not only includes the data
ports but also allows for the RTS signal to be picked up. In ad-
dition the Profibus module is equipped with a second set of
parallel data ports (X6.4) and the DIP switch for the terminat-
ing resistor which are accessible from the front.
Note: For more detailed information see the special Operating
Instructions of the various bus systems.
