5.8 Configuration of the dip-switch
Servo motor SM137D is equipped with two dip-switches, respectively called DSW1 and DSW2.
The dip-switches are used to set the Fieldbus address, operating modes, transmission speed and
line termination. In addition, they set the communication protocol.
The servo motor communication protocol can be selected using dip-switch DSW1.
The configuration of the dip-switches changes according to the communication protocol used.
To access the dip-switch, release the screws and remove the plastic window A.
Only change the configuration of the dip-switches when the board is not powered up
.
Once the configuration has been made, make sure the plastic window protecting the
dip-switches is closed properly, with the two screws tightened.
Don't over-tighten the screws, as you may damage the protective plastic window.
5.8.1 Configuration following a replacement
If you need to replace a servo-motor of a version no longer produced, version SM137D can be
made compatible with the previous version by configuring dip-switch DSW2 in the appropriate way.
Refer to the relative comparative paragraph “Compatibility for replacements” in appendix C “Spare
parts” for the codes of products that are compatible in the various versions and protocols.
To quickly and correctly configure the servo-motor replacing a compatible one, refer to the relevant
paragraph “Dip-switch configuration for replacements” in the appendix C “Spare parts”, where you
can find the settings that need to be made for each protocol.
