11.3 sercos II module
11.3.1 Product description
The sercos II module is used to connect the ARS 2300 servo drive to a sercos-compatible CNC
control. The communication on the sercos II bus uses a ring-shaped optical fibre link with transmission
rates of up to 16 Mbaud. If six servo drives are connected to one bus, set points and actual values
(position, speed and torque values) can be exchanged with the CNC control every 500 µs.
The sercos II module is supported solely in the
TECH 2
technology slot.
In addition to the sercos II module, the TECH 1 technology slot can also be used for the
I/O extension module EA88.
Additional technology modules will not be supported if the sercos II module is used.
If your specific requirements are more complex, please contact your sales partner in
order to find a solution for your particular application.
A special feature of the sercos II bus is the synchronisation of all the devices connected to the bus. If
several ARS 2300 servo drives are connected, the internal controller and output stages of the servo
drives operate in a phase-locked manner.
Via the 8-pole DIP switch the sercos II bus address can optionally be set. When restarted, the servo
drive checks whether there has been set a bus address via these switches (all switches in position
OFF

no bus address set). If no bus address has been set via the 8-pole DIP switches, the servo
drive uses the bus address set via the Metronix ServoCommander™ (menu: Parameters/Field bus/
sercos…).
Example for setting the bus address via the 8-pole DIP switch: Switches 1, 4 and 8 are active (in
position ON). From this the (decimal) bus address 137 (89h) is derived.
Switch 1:
2
0
 1
Switch 4: 2
3

8
Switch 8: 2
7
 128
Sum: 1 + 8 + 128 = 137
