Function:
Use a digital input signal or a fieldbus bit to
activate the enable reference mode and the
relative position mode.
This option selects the relative position mode
permanently. All positioning commands are
considered to be relative. Toggling option
[113] Enable Reference on a digital input or the
enable reference fieldbus bit triggers relative
positioning.
This option selects the enable reference mode
permanently. Any new position reference
triggers an absolute positioning command
with the selected position reference as target.
This option cannot be used with relative
positioning.
Function:
NOTICE
This parameter is available only with
software version 48.XX.
Select the behavior of the master offset in
synchronization mode.
The frequency converter adds the master offset
(parameter 3-26 Master Offset) to the position at
synchronization start. The offset command is
executed at every new synchronization start.
The frequency converter adds the master offset
(parameter 3-26 Master Offset) to the position at
synchronization start. The offset command is
executed with every enable master offset signal.
The frequency converter adds the master offset
(parameter 3-26 Master Offset) to the actual
synchronization position with every enable
master offset signal.
The master offset (parameter 3-26 Master Offset)
is relative or absolute depending on the relative
position signal on a digital input or the fieldbus
bit.
The master offset (parameter 3-26 Master Offset)
is relative to the home sensor signal. The offset
command is executed with the next home
sensor signal when the enable master offset
signal is active.
The master offset (parameter 3-26 Master Offset)
is relative to the touch sensor signal. The offset
command is executed with the next touch
sensor signal when the enable master offset
signal is active.

3.18.1 18-0* Maintenance Log

This group contains the last 10 preventive maintenance
events. Maintenance log 0 is the latest and maintenance
log 9 the oldest.
By selecting 1 of the logs and pressing [OK], the
maintenance item, action, and time of the occurrence are
shown in parameter 18-00 Maintenance Log: Item –
parameter 18-03 Maintenance Log: Date and Time.
The alarm log key allows access to both alarm log and
maintenance log.

Select the rotation direction for the absolute
position mode when parameter 17-76 Position
Axis Mode is set to [1] Rotary Axis. To use this
parameter, set parameter 4-10 Motor Speed
Direction to [2] Both directions.
The frequency converter selects the rotation
direction that provides the shortest route to the
target position.
Move to the target position in the forward
direction.
Move to the target position in the reverse
direction.
