Parameters 403
Auto falling
One of the above modes is selected automatically depending
on the pulse frequency as follows:
5
(Visible when an absolute encoder is selected)
Enables the encoder zero pulse for the absolute encoder input
(X42) of the FEN-11 interface module.
Note:
No zero pulse exists with serial interfaces, ie. when
parameter
is set to
,
,
or
Disable
Zero pulse disabled.
0
Enable
Zero pulse enabled.
1
(Visible when a resolver is selected)
Defines the number of pole pairs of the resolver.
1
1…32
Number of resolver pole pairs.
1 = 1
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects whether position estimation is used with encoder 1 to
increase position data resolution or not.
Disable
Measured position used. (The resolution is 4 × pulses per
revolution for quadrature encoders, 2 × pulses per revolution
for single-track encoders.)
0
Enable
Estimated position used. (Uses position interpolation;
extrapolated at the time of data request.)
1
(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
is set to
. When parameter
, 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 (
0
0…32
Number of bits used in position indication within one
revolution.
1 = 1
(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
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
No.
