Terminal assignment and commissioning
6.1
Electrical connection
The bus cover must rest fully against the housing and be firmly screwed in place.
For electrical connection, pull off the bus cover using the following method:
•
Release the fastening screws of the bus cover
•
Carefully loosen the bus cover and lift off in the axial direction
6.1.1
Setting the user address
The user address is set via the EEPROM. The node ID (user address) is defined in object 2101h. In addition,
it is possible to set the user address decimally using two rotary switches in the bus cover. If the switches are
at 0, the node ID from the EEPROM is used. As soon as the switch is set to a value, this set value is used as
the user address. The maximum number of users is 99.
•
Set the user address decimally using the two rotary switches 1 and 2 (default setting 00).
Example: 23
6.1.2
Setting the baud rate
The baud rate is defined in the object 2100h. In addition, it is possible here to set the baud rate using a
switch. The baud rate setting is performed on a binary basis via switches 1 to 3 of the 3-pin DIP switch in the
bus cover. The baud rate used from the EEPROM is ignored as soon as the switch for the user address is
not set to 0.

Terminating resistor
If the connected encoder/converter is the last device in the bus line, the bus must be terminated with a
resistor. The resistor is in the bus cover and is connected using a one-pole DIP switch. The terminating
resistor must be switched to "ON" at the last user with a 1-pole DIP switch (default setting OFF).
ON = Final user
OFF = User X
