Configuring Positioning Point Tables

The position values, travel speeds and acceleration and deceleration times are stored in tables
known as "point tables". We will now go through the steps required to configure and define a
point table.
Procedure:
Select the Point Table option from the Point-data menu.
Enter the values for the movements (position, speed, acceleration and deceleration times)
in the Point Table List window, using one line for each movement:
– Enter target position (a) in µm x 10
– Enter speed (b) in rpm.
– Enter acceleration/deceleration times (c) and (d) in ms as required for the motor's rated
Save the entries by clicking on the Write All button.
Fig. 3-5:
Make sure that the Aux. Func. value in every line is left at the default factory setting ("0") to
ensure that selecting a position value in the table does not inadvertently activate any subse-
quent table entries.
NOTES In the factory default settings the absolute value command system for the target positions is
activated with parameter PA01 "*STY". When this system is active all target position values
are referred to the physical home position. Alternatively you can also select the incremental
value command system. The absolute position detection system for the home return func-
tion can be set with parameter PA03 "*ABS" (see chapter 4.3).
Loading the factory defaults will not overwrite your point table entries.
