Scaled Feedback

For feedback not associated with an axis, a set of scaled feedback parameters are provided to optionally represent the feedback position in scaled units.

• FB Monitor PIN (FB#.SCALED.PIN) and FB Monitor POUT (FB#.SCALED.POUT)  specify the scaling ratio.
• Direction (FB#.SCALED.DIR) sets the direction of the scaled position.
• Offset (FB#.SCALED.OFFSET) sets an offset adjustment.
• Unit Label (FB#.SCALED.LABEL) is a short units text description.

The Scaled Position is calculated as follows:

FB#.SCALED.DIR	Direction Sign
0	1
1	-1

Dual-Loop

There are separate feedback sources for the current, velocity, and position loops. By default they’re all set to the current loop feedback source (AXIS#.IL.FBSOURCE). If a separate feedback is desired for the different loops, those sources can be set independently using AXIS#.VL.FBSOURCE and AXIS#.PL.FBSOURCE .

Electronic Gearing

For Electronic Gearing, AXIS#.GEAR.FBSOURCE is also available. See the Electronic Gearing feature for more information.
