Options
l
Encoder with AB track
The AB track provides incremental (square) track signals. This option must be
selected if you want to use a digital incremental encoder. It can be deselected if
your encoder only has Hall signals. In this case, the option
Encoder with Hall
signals
must be selected.
l
Encoder with index track
Usually, there is one index pulse during every revolution of a digital incremental
encoder. The index track ensures consistent precision in the case of incremental
encoder systems. If counting errors occur due to external interferences, they are
corrected when the index pulse occurs. Information as to whether the angle
encoder has such a pulse can be found on the data sheet of the angle encoder. If an
index track is included and connected, the index pulse function can be suppressed
by deselecting this checkbox.
Risk of injury due to uncontrolled drive movements.
The servo drive corrects the actual position if the index pulse is activated. In the case of
encoders with unsymmetrical index pulses, this may cause the drive to overspeed. This
is why, if in doubt, the index pulse evaluation should be deactivated.
Usually, linear motors do not include cyclic index pulses. However, there may be a
single index pulse that can be used for homing.
