17-92 Position Control Selection
Option:
Function:
[0]
*
No
Operation
Use a digital input signal or a fieldbus bit to
activate the enable reference mode and the
relative position mode.
[1]
Relative
Position
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.
[2]
Enable
Reference
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.
17-93 Master Offset Selection
Option:
Function:
NOTICE
This parameter is available only with
software version 48.XX.
Select the behavior of the master offset in
synchronization mode.
[0]
*
Absolute
Enabled
The frequency converter adds the master offset
(
) to the position at
synchronization start. The offset command is
executed at every new synchronization start.
[1]
Absolute
The frequency converter adds the master offset
(
) to the position at
synchronization start. The offset command is
executed with every enable master offset signal.
[2]
Relative
The frequency converter adds the master offset
(
) to the actual
synchronization position with every enable
master offset signal.
[3]
Selection
The master offset (
is relative or absolute depending on the relative
position signal on a digital input or the fieldbus
bit.
[4]
Relative
Home
Sensor
The 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.
[5]
Relative
Touch
Sensor
The 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.

Option:
Function:
NOTICE
This parameter is available only with
software version 48.XX.
Select the rotation direction for the absolute
position mode when
is set to
[1] Rotary Axis
. To use this
parameter, set
parameter 4-10 Motor Speed
Direction
to
[2] Both directions
.
[0]
*
Shortest The frequency converter selects the rotation
direction that provides the shortest route to the
target position.
[1]
Forward Move to the target position in the forward
direction.
[2]
Reverse
Move to the target position in the reverse
direction.
[3]
Direction The forward/reverse signal on a digital input or
fieldbus determines the rotation direction.
