Description
Estimated position used. (Uses position interpolation;
extrapolated at the time of data request.)
(Visible when 92.1 Encoder 1 type
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
position source is set to EnDat,
parameter 92.11 Absolute position source
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
Number of bits used in revolution count.
(Visible when 92.1 Encoder 1 type
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.
Last calculated speed used. (The calculation interval is
62.5 microseconds to 4 milliseconds.)
Estimated speed (estimated at the time of data
request) is used.
(Visible when 92.1 Encoder 1 type
Activates transient filtering for the encoder (changes
in direction of rotation are ignored above the selected
pulse frequency).
Change in direction of rotation allowed below 4880 Hz.
Change in direction of rotation allowed below 2440 Hz.
Change in direction of rotation allowed below 1220 Hz.
Change in direction of rotation allowed at any pulse
frequency.
(Visible when 92.1 Encoder 1 type
Defines the maximum pulse frequency of encoder 1.
