Many encoders deliver only one non-dierential signal, which has many disadvantages. To con-
vert it into a dierential signal you can use the dierential line driver. This converts the AB
signal into an A+A-B+B signal and thus signicantly increases interference immunity. Another
advantage of the driver is the possibility of connecting the encoder to the controller via a com-
mercially available Ethernet patch cable. This provides a very cost-eective, simple shielded
connection.
The line driver can be soldered directly to encoders of type HEDS or AMT103:
Encoder-Setings
Some encoder types can be set in the pulse rate, e.g. the type AMT103-V. Please refer to the
section on the encoder in this manual and set the desired pulse rate. Other encoders have a
xed pulse rate and cannot be set.
For example: The PIB408 Encoder already
delivers a dierential signal and has an
8mm axis already installed.
MOST IMPORTANT:
The pulse rate of the encoder must also be entered in the controller settings!
