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 only turns on during the initialization phase. If the feedback type cannot be automatically detected, the power supply is turned off, and remains off until an AXIS#.CLRFAULTS is issued (which restarts 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 remains on, unless a short is detected. This is useful for encoder types requiring calibration.
When an SFA feedback is selected with FB#.SELECT, it will automatically be updated with the latest SFA FPGA image if needed.
FB#.SELECT Input Values
Changing these input values manually sets the value of FB#.IDENTIFIED .
-
-
If the feedback setting fails, FB#.IDENTIFIED is automatically set to 0 (no feedback identified).
-
- If Axis 2 has been configured to use gantry command source (AXIS#.CMDSOURCE = 4) and the gantry is active (GANTRY.STATE = 3), if this keyword is changed, it will set the gantry state back to "pending homing" (GANTRY.STATE = 1). See GANTRY.HOME.REQUIRED documentation for more details.

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 is updated with the type of feedback found or 0 if no feedback can be found. |
| 1 | No Encoder | Use this if no feedback device is connected to the associated connector. |
