Yaskawa Z Pulse Drive Change

Print Print
  • Purpose Statement
  1. To insure the CNC Software System can register the z pulse from the Y axis encoder and confirm the sequence complete and allows machine referencing to take place in the Y axis
  2. To increase the "Z" axis pulse width of the C channel of Yaskawa Drives.
  3. Changes encoder pulse widths from 8192 pulses per revolution to 1024 pulses per revolution.
  • Scope
  1. Yaskawa Drives for ESAB Gantry Type Cutting Machines
  • Procedure
  1. Insert the digital operator panel into the serial port on the front of the drive amplifier.
  2. Power up the amplifier but do not enable the drives ( do not SHIFT/RAPID )
  3. On the digital operator panel hold down the JOG button at the same time while pressing:
    1. Press ( down arrow ) three times
    2. Press ( up arrow ) two times
    3. Press ( data / enter) two times

    NOTE: This accesses a protected area not available other than through the digital operator panel.

  4. Press DISPL/SET
  5. Using the < > up / down arrows increment the C address to 6A
  6. Press DATA/ENTER
  7. The contents of this location should be displayed ( H.840A in HEX )
  8. Using the < > arrows to change the flashing character to the second least significant bit (0).
  9. Increment this hex value to 2
  10. Press DSPL/SET (The display will flash 3 or 4 times as it writes the new contents to memory)
  11. Press DATA/ENTER to return to the address.
  12. Power down the drive system
  13. Power up the drive system
