AXIS#.MOTOR.PITCH

Description

This parameter is used with linear encoders. It defines a distance in millimeters which is determined by how the linear enocoder is used.

  • When used with a linear motor, it defines the pole-to-pole pitch. The pitch is the distance between two similar poles. Kollmorgen linear motors have a pitch of 32mm.

  • When using a linear encoder in a dual loop configuration in which the linear encoder is used as a secondary position feedback, the distance specified is equal to the distance the linear encoder travels given one rotation of the rotary motor.


  • This parameter is required to be configured for AXIS#.MOTOR.TYPE = 1 or when using a linear encoder as the AXIS#.PL.FBSOURCE.

Action Version Notes
Implemented 02-00-00-000
Added dual loop behavior 02-09-03-000 AXIS#.MOTOR.PITCH was not previously included in the resolution calculation when using a linear encoder only as a position source. In order to relate the rotary motor with the linear encoder for proper control, this parameter is now required to be set.
