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.

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).

Notes

–1

 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 deviceClosed A process whereby some proportion of the output signal of a system is passed (fed back) to the input. In automation, a device coupled to each motor to provide indication of the motor's shaft angle, for use in commutating the motor and controlling its speed and position is connected to the associated connector.

It is a way of connecting instruments in a plant design Parameter Index Sub-Index Data Type Float Scale Units Access PDOClosed PDO is a type of protocol frame used in some fieldbuses. A PDO contains one or more object dictionary entries, which define the application data transferred between devices. Mappable
