Sigma 1 Servomotors

Required to run a new Haas rotary on a Haas mill built in 2010 or earlier

This option replaces the default Sigma 5 servomotor drive(s) with a Sigma 1 servomotor drive(s). Required for using the rotary table on 2010 or older Haas mills, or with servo control units built prior to May 2011. Requires a Haas mill with software version 17.xx or earlier.

  • Mills with software versions older than 18.00 must use Sigma 1 rotaries
  • Mills with software version 18.00 or newer may use Sigma 5 rotaries
  • Sigma 1 rotaries can be used on mills with any software version, but do not offer the advantages of Sigma 5 rotaries (scale feedback on TRs)
