1Estimated position used. (Uses position interpolation;
extrapolated at the time of data request.)
Enable
0 / uint16(Visible when 92.1 Encoder 1 type = Absolute encoder)
Defines the number of bits used in revolution counting
with a multiturn encoder. For example, a setting of 12
bits would support counting up to 4096 revolutions.
The value is used when parameter 92.11 Absolute
position source is set to EnDat, Hiperface or SSI. When
parameter 92.11 Absolute position source is set to
Tamagawa, setting this parameter to a non-zero value
activates multiturn data requesting.
Note: With an EnDat or HIPERFACE encoder and FEN-11
FPGA version VIE12200 or later, this parameter is
automatically set upon validation of encoder settings
(91.10 Encoder parameter refresh).

Disable / uint16(Visible when 92.1 Encoder 1 type = HTL 1)
Selects whether calculated or estimated speed is used.
Estimation increases the speed ripple in steady state
operation, but improves the dynamics.
Note: This parameter is not effective with FEN-xx
modules with FPGA version VIEx 2000 or later.

Enable
4880Hz / uint16(Visible when 92.1 Encoder 1 type = HTL 1)
Activates transient filtering for the encoder (changes
in direction of rotation are ignored above the selected
pulse frequency).
