NORDAC SK 1000E Hardware description

BU1100 GB
Up to 16 different addresses can be selected via the servo controller DIP switches, these addresses are
only read in when the power supply for the servo controller is switched on. Terminating resistors are
integrated and can be set or switched on like the address pre-selection via the DIP switches. These
switches are located under the opened plastic cover on the front panel of the servo controller. The
quadruple DIP switch (S1) sets the address pre-selection and the twin DIP switch (S2) enables/disables
the terminating resistor.

Address settings for the bus on the quadruple DIP switch
The addresses for CAN nodes are increased by 1 in the servo controller, i.e., when 0 is set as an
address with the DIP switch, the servo controller will have the CAN node address “1”.
The baud rate can be set to 10K, 20k, 50k, 125k, 250k, 500kBaud and 1MBaud. The default rate is
500kBaud, an optional variant is available with 1MBaud. The settings are made via the supplied NORD
SERV operating software.
