1 General

Safety SIL3 absolute rotary encoder with PROFIBUS-DP interface.

2 Hardware settings

2.1 PROFIBUS Shield

The cable needs to be connected to an EMC rail close to the encoder

If the measuring System is the last slave in the PROFIBUS segment, you need a termination plug.

3 Hardware Configuration

Adjustments:

• F-Dest_Add = PB address + 500 (501...599 is possible)
• F_WD_Time = 800
• F_iPar_CRC = depends on the sense of direction
  • CW = 1132081116
    • HEX: 437A2FDC
  • CCW = 880615242
    • HEX: 347D1F4A

• Set like in the picture above. Only the direction you can adjust. Take care that you have to modify the CRC according to this setting!
• Safety rotation setting must match with the normal rotation setting. (Safety CW, Normal settings also CW)
  • Vorlauf -> CW
  • Rücklauf -> CCW

4 Communication and Calibration

4.1 Communication to the S7

Standard address range:

PIW xxx + 6  = Encoder Position

Safety address range:

IW xxx + 8  = Encoder Position
QW  xxx + 6  = CalSet
Q  xxx + 1.0  = Cal Run

4.2 Calibrate the actual Position

The Calibration is done via the Safety Programm, it can only be carried out when an emergency stop is active. In case of troubles, please contact Template:EEC-Support
