Страница: 466 / 664

466 Parameters
Enable Estimated position used. (Uses position interpolation;
extrapolated at the time of data request.) 1
92.13 Position data width (Visible when an absolute encoder is selected)
Defines the number of bits used to indicate position within
one revolution. For example, a setting of 15 bits corresponds
to 32768 positions per revolution.
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 , this
parameter is internally set to 17.
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 ).
0
0…32 Number of bits used in position indication within one
revolution. 1 = 1
92.14 Speed estimation
enable (Visible when a TTL, TTL+ or HTL encoder is selected)
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.
Disable
Disable Last calculated speed used. (The calculation interval is 62.5
microseconds to 4 milliseconds.) 0
Enable Estimated speed (estimated at the time of data request) is
used. 1
92.14 Revolution data
width (Visible when an absolute encoder is selected)
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 ).
0
0…32 Number of bits used in revolution count. 1 = 1
92.15 Transient filter (Visible when a TTL, TTL+ or HTL encoder is selected)
Activates transient filtering for the encoder (changes in
direction of rotation are ignored above the selected pulse
frequency).
4880 Hz
4880 Hz Change in direction of rotation allowed below 4880 Hz. 0
2440 Hz Change in direction of rotation allowed below 2440 Hz. 1
1220 Hz Change in direction of rotation allowed below 1220 Hz. 2
Disabled Change in direction of rotation allowed at any pulse
frequency. 3
92.16 Encoder 1 supply
voltage (Visible when parameter 92.01 Encoder 1 type = HTL 1 or
HTL 2 )
Selects the power supply voltage for encoder 1.
