Connection example: HTL encoder, bipolar, with reference signal
This example shows the connection assignment on the sensor module. The terminals of the
sensor module are wired to the customer terminal strip. For further information, see the circuit
manual.

Connection example: HTL encoder, bipolar, with reference signal
Use a bipolar connection. The unipolar connection should only be employed when the encoder
type being used does not provide push-pull signals.

Connecting the external safety loop
You can extend the "Safety shutdown" function using external devices. For instance, using an
Emergency Stop pushbutton or isolated contacts from the excitation. This is the reason that the
contacts of the safety circuit are connected to terminals. Precise data on these terminals is
provided in the circuit diagram and terminal diagram.
WARNING
Danger due to high voltages
In spite of a safety shutdown function, the drive may still be operational or high voltages may
still be present.
Residual voltages can result in death, severe injury or significant material damage. The "Safety
shutdown" function can neither ensure that the drive stops immediately nor can it ensure that
residual voltages do not still exist at the output terminals and within the unit.
• Make sure that the drive no longer rotates and that there are no high voltages present.
