4.4 Connecting encoders
NOTICE
Danger of damage to the device and encoder damage
due to incorrect voltage supply range and incorrect
wiring!
Note the voltage supply range of the connected
encoder.
Check whether the cable between the encoder and
device is correctly wired.
The cable between the encoder and the device must
not be connected or disconnected while under power.
The connection and operation of the device with
encoders that are not from HEIDENHAIN is the user‘s
own risk.
Connections
Encoders with a 15-pin interface are connected to
encoder input X1 on the front panel.
When connected to the control loop, encoder output X2
is used for encoders with a 15-pin interface.
Encoders with 8+2-pin DRIVE-CLiQ interfaces are
connected to encoder input X4 on the front panel.
For information on the location of the connections, see
"Product overview", page 23.
The pin layouts of the connecting cables are described in
the catalog.
Notes on the signal assignment of the pins in the

= Power supply
Sensor: The sensor lines are connected
internally with the corresponding voltage
supply, depending on the settings in the
ATS software ("ATS Software Operating
Instructions" document, see "Notes on reading
the documentation", page 18).
