9.2 Analog Output
The 12 bit analog output operates proportional to the position value. Depending on the selected interface op-
tion (see

11), the output is designed for operation with voltage or current.
9.2.1 Scaling of the Analog Output
The resolution to the analog interface is 700 µm. In the delivery state, each position increment of 700 µm corre-
sponds to a change of one bit in the DAC value.
In order to adapt the system to the desired application, two positions must be learned during commissioning
(TEACH procedure). The lowest TEACH position (min) and all lower TEACH positions are assigned to the DA
converter value "0". The uppermost TEACH position (Max) and all positions above are assigned to the DAC
value "4095". Within the two TEACH positions, each internal position step of 700 µm corresponds to a DAC
change of 4095 / (uppermost teach position - lowermost teach position).
For more information about the TEACH positions, see

9.2.2 Connections Analog Output
Depending on the order specification, the connections are made via open cable ends or via an 5-pin M12
round connector which is attached to the end of the signal cable.
