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.

| 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. |
