Connections
The unit provides a 9-pin Sub-D connector (female on the unit site) for connection of the
sine/cosine sensor. For easy power supply of the encoder, an external jumper allows to switch
an auxiliary voltage of either 5.2 volts or approx. 20 volts to the same connector. Also the mean
voltage is available on the connector pins, allowing also the use of sensors with non-
differential sinus output.
The incremental output impulses are available with RS422 standard and HTL standard (push-
pull) at the same time, and one output of both or both outputs at a time may be used, quite
according to the application.
All inputs and outputs as well as the power supply refer to the same
reference potential (GND)!
In case of errors the Error Output switches to HIGH. At the same time the yellow front LED will
be lit.
To release an Error state, a HIGH signal must be applied to the “Error Release” input (PNP, HTL,
a positive signal of 10-30 volts will release the error). Errors may be cleared also by pushing the
small button on the top site of the unit.
The unit operates with a 18 – 30 volts DC power applied to terminals 5 (+) and 6 (-)
