6 Checking incremental encoders
6.1 General information
As of the ATS software version 2.06.xx functional checks can be performed on HEIDENHAIN
incremental encoders with the following interfaces:
 Analog output signals 11 µApp, 1 Vpp
 Digital square-wave output signals TTL and HTL (with additional adapter)
Only the PWM 20 supports the inspection of incremental encoders!

6.2.1 Connecting the encoder
8 Connect the encoder to the test unit with an adapter cable.
8
Double-click "Connect encoder" in the ATS main menu.
The encoder selection window offers the possibility of connecting the encoder through its
ID number (entry in database) or - if the ID is not in the database - through "Manual settings".
In the latter case the interface must be selected by hand.
Note
Adapter cables: See User's Manual "PWM 20 Cable and Connection Technology".
Note
See section “Setting up a connection to the encoder” on page 28 for further details.
DANGER
If the manual setting of the encoder parameters does not match the connected encoder, the
encoder, the PWM 20 or the computer could be damaged.
Note
For the encoder data, please refer to the respective mounting instructions or machine
documentation. Contact the machine manufacturer or the HEIDENHAIN Service.
