FB#.INFO

Description

Provides information about the feedback device 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 connected to the drive.

The large range of AKD2Gfeedback devices supports vary in their capabilities and information the drive can determine from the feedback. For devices like HIPERFACE DSL and EnDat, the interface supports the ability to read information from the device whereas resolvers and incremental encoders where no additional information can be read beyond position. FB#.INFO provides a list of this extra information where available as each device has different capabilities the information provided varies.

Example

For example, an EnDat device reports.

-->FB3.INFO
Type: 31 (EnDat Digital)
Safety: SIL3
Encoder model: 14 (Multi-turn rotary with gears)
Model Number: 826980-52
Serial Number: -66368787-A
Multi-turn bits: 12
EnDat protocol: 2.2
Ordering designation: EnDat22
-->

And a HIPERFACE DSL device reports.

-->FB1.INFO
Type: 46 (HIPERFACE DSL)
Safety: None
Model Number: EEM37-0KF0A017A
Serial Number: U1234111A
-->

 

The following are the rows that FB#.INFO could show:

Name	Description

Safety	None, SIL2 or SIL3. What is the maximum safety level that this device is capable of.
Model number	The model number read from the feedback device.
Serial number	The serial number read from the feedback device.
Cycles per revolution	The number of sine cycles per revolution.
Multi-turn bits	The number of turns that this device maintains while the device is powered down.
EnDat protocol	2.1 or 2.2
