No.
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.

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).
