4. Dual position feedback function for servo mode [9D50/M, 9D53/D, 9D70/C]
4.1. General
Dual position feedback function for servo mode (rigid tapping / spindle positioning) is added.
See “FANUC AC SPINDLE MOTOR αi series PARAMETER MANUAL : B-65280EN” for detailed
specification of dual position feedback function.
Remark
* Dual position feedback function is unavailable in SUB spindle of Spindle Switching Control.
4.2. Related parameters
4.2.1. Remark
Parameters listed in table below are the same with parameters related to dual position feedback for
Cs contouring control.

Primary delay time constant in dual position feedback [for servo mode]
Unit of data ： 1msec
Valid data range ： 0 to 32767
Standard setting ： 0
Sets primary delay time constant in dual position feedback for servo
mode (rigid tapping / spindle positioning).
If hunting occurs during acceleration / deceleration, set a larger
value.
Setting “0” provides control equivalent to closed loop.
Setting “32767” provides control equivalent to semi-closed loop.
