3 How to Configure the System
3.1 Configure the PROFIBUS Network
All PROFIBUS stations that are connected to the same network must have a unique station address.
The PROFIBUS address of the frequency converter can be selected via:
- Hardware switches
- par. PB-18 Node Address
- The PROFIBUS command SSA Set Station Address
3.1.1 Setting the PROFIBUS Address using the Hardware Switches
Using the hardware switches it is possible to select an address range from 0 to 125 (factory setting 127) according to the table below:
Switch 8 7 6 5 4 3 2 1
Address value Not used +64 +32 +16 +8 +4 +2 +1
E.g. address 5 Not used OFF OFF OFF OFF ON OFF ON
E.g. address 35 Not used OFF ON OFF OFF OFF ON ON
E.g. address 82 Not used ON OFF ON OFF OFF ON OFF
NB!
Switch off the power supply before changing the hardware switches.
The address change will come into effect at the next power-up, and can be
read in par. PB-18 Node Address.
Note the location and sequence of the hardware switches as illustrated in the
figure opposite.
Setting the PROFIBUS Address via par. PB-18 Node Address :
Setting the address via par. PB-18 Node Address or the Profibus SSA-command is possible, if the hardware switches are set to 126 or 127 (factory switch setting).
The address change will come into effect at the next power-up.
Setting the PROFIBUS Address with Set Station Address Command:
Setting the address via the "Set Station Address" command is possible, if the hardware switch is set to 126 or 127 (factory switch setting). Using the "Set Station
Address" command it is possible to lock the programmed address, which makes it impossible to change the address using this command. The address setting
can be unlocked by changing the par. PB-18 Node Address or the address switch, followed by a power cycle. A new address is effective immediately after the "Set
Station Address" command.
