4.3.1 Preparations for the teach procedure

Teach procedure

During the teach procedure movement is made at first
cyclically and slowly to the end positions P.01 and P.02. In
this way the SPC-11 learns the mechanical end positions and
some characteristic system values such as friction and
hysteresis. The SPC11 saves these values in the integrated
EEPROM.

In order to check the set parameters for plausibility, the
moveable mass is first brought dynamically into the centre of
the positioning stroke used and then moved to just in front of
end position P.01.

Please note
When an incremental path measuring system is used
(e.g. with type DNCI-...-...): During the teach procedure,
movement is made to the end positions P.01 and P.02. This
creates the relationship between measurement variable
and current position. Reference travel is not necessary.

The teach procedure is concluded when the moveable mass is
pressed against end position P.01 and the output O1 supplies
a 1-signal.

Before commissioning can be undertaken, the pneumatic
drive must be ready for operation. The teach procedure
should be carried out with maximum permitted mass load.
During the teach procedure there must be a 0-signal at inputs
P.01 to P.04.

Proceed as follows in order to prepare the teach procedure:

1. Check the complete system structure, especially the drive

tubing (see chapter 3). Special specifications for your
drive can be found in the “Drive-Specific Supplement”.

2. Check the electrical circuitry.
