FB#.PRES
Description
FB#.PRES reports the resolution of FB#.P. This can be useful to determine if the value FB#.P is reporting are correct and for calculating scaling parameters in custom units.
For rotary motors this is always 232 counts/rev. For linear motors or dual loop applications where the feedback is assigned to an axis using AXIS#.IL.FBSOURCE, AXIS#.VL.FBSOURCE , or AXIS#.PL.FBSOURCE , it will be derived from AXIS#.MOTOR.PITCH and give counts/mm regardless of the encoder’s actual resolution. For linear encoders not attached to an axis, it will be in counts/mm using the encoder’s resolution matching FB#.RES.
Examples
- Any Rotary:
- Linear Motor ued as AXIS#.IL.FBSOURCE with AXIS#.MOTOR.PITCH = 32mm between poles (default):
- Linear Encoder used as AXIS#.PL.FBSOURCE with AXIS#.MOTOR.PITCH = 1mm movement per 1 rev of primary rotary motor:
- Linear Encoder not assigned to an axis using an EnDat Analog 20,000nm/line:
