Initialize Counting Direction; Initializing Home Position - BONFIGLIOLI Active Cube User Manual

6.6.2 Initialize counting direction

First check if the counting direction of the user units meets the requirements. You can
change the counting direction by inverting the parameter
513 (e.g. by inverting parameter
tor
to -200.00).

6.6.3 Initializing home position

For positioning application, a certain point of the system is typically defined as the
home position. After checking the correct reference system of the positioning and
linear encoder (see Chapter 6.6.1) and setting the counting direction, the home posi-
tion can be initialized.
Move (e.g. in JOG mode) to the required system home position. At this position, stop
the drive. Set parameter
Note:
Now, read the value in parameter

Example:
Act. Position
Once you have set up the home position offset, check the system for correct function
again (see chapter 6.6.1).
If required for the application, set up the software limit switches now.

limit switches are used or in the case of feedback to a PLC, this can result
in warnings or application errors. For this reasons, after changing the
parameters of the reference system and the encoder, always check the
1108, considering the permissible travel distance (e.g.

Referencing using an absolute value encoder is not necessary after com-
pletion of first commissioning. The referencing setting
1220 with setting "10 – No referencing required" can be used after
mode
initialization.
