Description
One of the above modes is selected automatically
depending on the pulse frequency as follows:
Pulse frequency of the

< 2442 Hz
2442...4884 Hz
> 4884 Hz
(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, i.e. when

Zero pulse enabled.
(Visible when a resolver is selected)
Defines the number of pole pairs of the resolver.
Number of resolver pole pairs.
(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.
Measured position used. (The resolution is 4 × pulses per
revolution for quadrature encoders, 2 × pulses per revolution
for single-track encoders.)
Estimated position used. (Uses position interpolation;
extrapolated at the time of data request.)
(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.

Number of bits used in position indication within one
revolution.
(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.
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.
