3.6.11 Transmit preset value
Using this parameter you can define whether the preset value (see section 3.6.17 on
page 40) is transmitted on switching on or initializing the encoder. You will find an
example for setting a preset value in section 4.4.2 from page 48.
Enable: The preset value is transmitted on switching on or initializing the encoder
into the parameter 65.000. The preset value can be changed in operation via
acyclic process data (see section 3.5 on page 24 and Table 35 on page 36).
Disable: The parameter is not transmitted on switching on or initializing the
encoder.
The preset value is only used when the related bits of the sensor 1 control word
G1_STW are set (see Table 14 on page 20) and bit 10 in control word STW2_ENC is set
(see Table 21 on page 23).
3.6.12 Round axis functionality
The round axis functionality removes the restriction that the total resolution must be 2ⁿ
times the Steps per revolution. The shaft is considered as an endless shaft.
The steps per revolution are not configured directly, instead the nominator and divisor
for the number of revolutions are defined.
The total measuring range can be scaled from 1 … 1,073,741,824 as an integer.
3.6.13 Number of revolutions, nominator for the round axis functionality
The nominator can be scaled from 1 … 2,048 as an integer. The default factory setting
for the nominator is 2,048.
3.6.14 Number of revolutions, divisor for the round axis functionality
The divisor can be scaled from 1 … 65,535 as an integer. The default factory setting for
the divisor is 1.
3.6.15 Speed filter, sampling interval
The speed value is calculated as an average value and output. The sampling interval
defines the time between measurements and how measurements are made. It can be
between 1 and 100 ms.
3.6.16 Speed filter, number of measurements
The number of measurements defines the number of measured values from which the
average speed is calculated. The number can be 1 to 200.
3.6.17 Preset value
The Preset value parameter contains the value that is transmitted to the encoder with
the parameter Transmit preset value (see section 3.6.11 on page 40).
