FB#.SELECT
Description
FB#.SELECT sets the feedback type manually (see FB#.IDENTIFIED ) or allows the drive to automatically identify the feedback type on power up.
Power Supply Notes:
If FB#.SELECT = -1, the power supply will only turn on during the initialization phase. If the feedback type cannot be automatically detected, the power supply will be turned off, and remain off until a AXIS#.CLRFAULTS is issued (which will re-start the FB initialization), or FB#.SELECT is manually set to a specific feedback type.
When FB#.SELECT is manually set to a specific feedback type, the FB power supply will remain on, unless a short is detected. This is useful for encoder types that may require calibration.
FB#.SELECT Input Values
Changing these input values will manually set the value of FB#.IDENTIFIED .

If the feedback setting fails, FB#.IDENTIFIED is automatically set to 0 (no feedback identified).

Auto-identify | The drive automatically identifies the type of feedback as part of the power up process. Note some feedback types cannot be automatically identified so the exact feedback needs to be selected. If auto identify is selected FB#.IDENTIFIED will be updated with the type of feedback found or 0 if no feedback can be found. |
