4
Notes on Control Word One

• 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

5
Jogging Axis

• 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

6
Verify Jogging of Axis

• Open Jog Folder to View Jogging
• All Motion Functions will be under Basis
  Positioner Folder

7
Verify Jogging of Axis

• 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

8
Jogging Setpoints

• Click on Configure Jog Setpoints
• Adjust setpoints if needed

9
Homing Axis for Absolute Value Encoders

• 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
