February 2002
In some cases a new reference mark may have to be assigned to an axis, e.g.
if an axis is mechanically fixed and the encoder is moved. Since due to the
mechanical fixing the position of the axis cannot be changed, you can assign
it a new reference value:
7
Enter the new reference value in Module 9147.
Module 9147 Assigning the reference value to an axis
If a new reference value is assigned to an axis, the corresponding bit is reset
in W1032.
Call:
PS B/W/D/K <>Axis number>
0 to 8: Axes 1 to 9
PS B/W/D/K <>New reference value in 0.1 µm>

Error detection:
Marker Value Meaning
M4203 0 No error
1 Error code in W1022
W1022 2 Invalid axis number
21 Missing strobe in M4176 = 1
24 Module was called in a spawn job or submit job
In machine parameters, you define the process of traversing the reference
marks:
7 In MP1320.x and MP1330.x (for rotary encoders also in MP1331.x) you
define the direction and velocity for traversing the reference marks.
7
In MP1340.x you define the sequence of axes for traversing the reference
marks.
7 With MP1350.x you select the type of reference marks.
If it is not possible to use the reference mark of the encoder, for example due
to an unsuitable transmission ratio between the motor and rotary axis, then
you can use an external reference pulse:
7
In MP4130.x, define the fast PLC input for the external reference pulse
7 For the corresponding axis in MP1360.x, enter the number of the fast PLC
input
7
Enter MP1350.x = 6 for the corresponding axis
