Connections for encoders
The encoder is connected to the input X1. The pin layout of the
15-pin D-sub female connector is as follows:

The power supply of the encoder (pin 4) is adjustable and
switchable per software. To avoid damage to the encoder,
ensure that the correct supply voltage is selected.
Remember also that the encoder must not be connected or
disconnected while under power.
The encoder output X2 is intended for special testing
purposes only and must remain free.
Connection for external functions
For external functions, a 4-pin female connection is available
through which the recording of measured values can be
externally controlled. The required connector can be ordered
from HEIDENHAIN under the part number Id. Nr. 282 168-01.
The signals are arranged as follows (view of the connection
from outside):

Input: Latch pulse for absolute value
Input: Latch pulse for incremental value
