1 General[edit | edit source]
Absolute Encoder with magnetic scanning unit, with PROFIBUS-DP interface. Various configurations are possible via the S7 Hardware configuration.
CMV=Solid Shaft
CMS=Integrated Claw Coupling
This encoder is used e.g. for the MDO stretching gap spindle position.
2 PROFIBUS Shield[edit | edit source]
Recheck that the PROFIBUS shielding is connected proper.
3 Bus Termination[edit | edit source]
If the measuring System is the last slave in the PROFIBUS segment, the bus is to be terminated withthe termination switch = ON. In this state, the subsequent PROFIBUS is decoupled.

4 Bus Address[edit | edit source]
Valid PROFIBUS addresses: 3 - 99
100: Setting the 1st position
101: Setting the 10th position
The device does not start up with an invalid station address, LEDs = OFF.

5 LED Diagnostic[edit | edit source]
The measuring system has two LEDs in the connection hood. A red LED (Bus Fail) to display faults and a green LED (Bus Run) to display status information. When the measuring system starts up, both LEDs flash briefly. The display then depends on the operational state.
6 Hardwareconfigs Settings[edit | edit source]
Check always parameter in the hardwareconfig: Template:Image
In the SCL software the POS_DIV_ACT must be same like the Steps per Revolution in the Hardwareconfig:
FUNCTION "StrMdo_Sga" : VOID CONST POS_FACTOR_ACT :=1.0; // distance revolution [mm] POS_DIV_ACT :=100.0; // raw input steps per revolution, must match hardware config setting POS_OFF_ACT :=-5.0; // use small negative value here to prevent encoder overflow at values slightly less than 0 [mm] END_CONST
If the Hardwareconfigs don't work with the settings, only then you set:
Step per Revolution = 10 Total measuring range = 32768
and adjust the SCL code also
