Def / Type
FbEq 16b / 32b Description Name / Range /
Selection 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 ).
Revolution data
width 92.14
1 = 1 / 1 = 1 Number of bits used in revolution count. 0...32
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.
Speed estimation
enable 92.14
0 Last calculated speed used. (The calculation interval is
62.5 microseconds to 4 milliseconds.) Disable
1 Estimated speed (estimated at the time of data
request) is used. 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).
Transient filter 92.15
0 Change in direction of rotation allowed below 4880 Hz. 4880Hz
1 Change in direction of rotation allowed below 2440 Hz. 2440Hz
2 Change in direction of rotation allowed below 1220 Hz. 1220Hz
3 Change in direction of rotation allowed at any pulse
frequency. Disabled
0 kHz / uint16 (Visible when 92.1 Encoder 1 type = HTL 1 )
Defines the maximum pulse frequency of encoder 1.
Accepted pulse freq
of encoder 1 92.17
1 = 1 kHz / 1 = 1 kHz Pulse frequency. 0...300 kHz
A, B / uint16 (Visible when 92.1 Encoder 1 type = HTL 1 )
Selects which encoder cable channels and wires are
monitored for wiring faults.
