Product description
3.5.7
Preset
The preset function is used to set the encoder to a predefined start position. With the aid
of a preset value the encoder can be set to any position within the measuring range.
The preset value can be set in the following manner:
using the preset push-button
using an acyclic explicit message
During this process the preset value is transferred as an attribute (ID19) of the Position
Sensor Object.
Only set a preset value when the encoder is at standstill.
Immediately after triggering the preset function, check whether there is a hazard from
the machine or system in which the encoder is integrated!
The preset function results in an immediate change in the position value output by the
encoder. This change could cause an unexpected movement that may result in a hazard
for persons or damage to the system or other items.
3.5.8
Velocity measuring unit
Using this parameter you can define the units in which the velocity is transmitted.
Possible units are:
counts/s
counts/ms
turns/s
turns/min
turns/h
The factory setting is
turns/min
.
3.5.9
Round axis functionality
The round axis functionality removes the restriction that the total resolution must be 2
H
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.
3.5.10
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.
3.5.11
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.
