  1. EZ Positioning with SINAMICS S120Testing Application

  2. Use VAR table in S7 Manager with Starter Diagnostics Open the VAR Table Online* Open Starter Online Right Click on False of Bit 0.0 and force to 1. *VAR Table included is addressed to DB120 if your test is for different DB you will need to edit VAR table Verify Control Word One

  3. Open Control Logic in Starter and Observe Bit 0 Toggle Bit O ON / OFF with VAR Table Off2, OFF3, and Enable are set Initially to 1 in the DB Initial Value can be changed by user OFF2 is Coast to Stop OFF3 is Quick Ramp Down Stop Enable is Pulse Enable to Drive Verify Control Word One

  4. Sequence order for Bits during Operation Bit 10 is High for PLC Control Off2, OFF3, and Enable are set to 1 OFF1 (Bit 0) Transitions to 1 and remains high Control Word 1 is needed for Operation Notes on Control Word One

  5. Use the VAR Table to Jog the axis Control Word 1 Bit 0 must be ON for Operation Set Bit 4.0 (Jog1) to True Override must be Changed to set Value (E.g. 4000 Hex) Initial DB value for Accel and Decel is 4000 Hex Use Bit 62.1 for Jog 2 Jogging Axis

  6. Open Jog Folder to View Jogging All Motion Functions will be under Basis Positioner Folder Verify Jogging of Axis

  7. Check Both Analog and Digital Setpoints Check Digital Setpoints and Checkback with Radio Buttons Check Analog Setpoints to see Override Velocity value Open Diagnostics Folder for more information Incremental Jogging can be set with a bit in the Instance DB Verify Jogging of Axis

  8. Click on Configure Jog Setpoints Adjust setpoints if needed Jogging Setpoints

  9. *Homing for Incremental Encoders on next Slide Jog the Axis to the Desired Home Position Turn off JOG and ON bits in the VAR chart Open the Homing Folder (Basis Positioner / Homing) Click on the Homing Graphic for Active and Passive 1 Choose Active Homing 2 Perform Absolute Value Calibration Homing Axis for Absolute Value Encoders* 1 2 3

  10. Select a Digital Input for Proximity Signal Select a Digital Input for External Zero Mark Incremental Encoder Homing – Note: Exercise uses absolute encoder

  11. Test digital Input from Switch Box Verify the Operation of the Digital Input for Zero Mark Incremental Encoder Homing

  12. Start Drive with DB Bit 0.0 Start Referencing with DB bit 4.1 Positive Direction for Homing is DB Bit 65.3 = 0 Force Drive External Zero Marker in Previous Screen Drive Should stop and have Homing Position Set Homing Axis for Incremental Encoders

  13. Use VAR Table to Run drive is Setup Mode Sequence for Setup Mode Set Control Word 1 in Operation (OFF1) Bit 10.1 MDI_Setup Bit = 1 Choose a Direction Fwd or Backward (10.3 or 10.4) Bit 10.7 Intermediate_Stop = 1 Bit 10.0 MDI_Start = 1 Bit 10.5 Edge_Trigger = 1 (Positive transition) Setup Mode – Direct Setpoint Spec. / MDI

  14. Use Direct Setpoint Specification / MDI Folder in Starter Check the Analog and Digital Signals during Setup / MDI Setup Mode – Direct Setpoint Spec. / MDI • Configure MDI Positioning Velocity • Open Configure MDI Fixed Setpoints

  15. Use VAR Table to Run drive is Relative Positioning Sequence for Relative Positioning Set Control Word 1 in Operation (OFF1) Bit 10.1 MDI_Setup Bit = 0 Bit 10.2 Position_Type = 0 (Relative) Bit 10.7 Intermediate_Stop = 1 Bit 10.0 MDI_Start = 1 MDI Velocity Override = Desired Override MDI Position DB Double Word 6 = Desired Position Move (Relative) Bit 10.5 Edge_Trigger = 1 (Positive transition) MDI Positioning - Relative

  16. Use Direct Setpoint Specification / MDI Folder in Starter Check the Analog and Digital Signals during Setup / MDI MDI Positioning Relative • Note Positive Edge Required for Relative Positioning

  17. Use VAR Table to Run drive is Absolute Positioning Sequence for Absolute Positioning Set Control Word 1 in Operation (OFF1) Bit 10.1 MDI_Setup Bit = 0 Bit 10.2 Position_Type = 1 (Absolute) Bit 10.7 Intermediate_Stop = 1 Bit 10.0 MDI_Start = 1 MDI Velocity Override DB Word 2 = Desired Override MDI Position DB Double Word 6 = Desired Position Bit 10.5 Edge_Trigger or 10.6 Constant_Trigger can be Used Note: Axis will move if new position given and Constant Trigger used MDI Positioning – Absolute

  18. Use Direct Setpoint Specification / MDI Folder in Starter Check the Analog and Digital Signals during Setup / MDI MDI Positioning Absolute • Note Edge Type Trigger or Continuous can be used for Absolute Positioning

  19. Set Up Traversing Block in Starter Open Traversing Blocks Editor under Traversing Blocks Folder See Next page for Block Editor Traversing Block

  20. Set Up Traversing Block in Starter Edit a few Blocks for Testing –See Example Below Blocks can be continuous or Single Block Execution Note the Advance Field for type of Execution In Job Field - Value of Wait or Go To (Block #) Possible Traversing Block

  21. Use VAR Table to Run Traversing Blocks Sequence for Traversing Set Control Word 1 in Operation (OFF1) Bit 10.0 MDI_Start = 0 Bit 10.7 Intermediate Stop = 1 Bit 64.7 Traverse Start DB Word 66 Traversing Bit to Start (E.g. = Block 1) Traversing Blocks

  22. Diagnostics Mentioned in the VAR Table These Bits and Words can be used in PLC Logic FB 120 Diagnostics

  23. FB 120 Block View Thank You!
