The four speed sensor inputs of the EM-ENC-03 expansion module can be set via the
parameter
operation mode for the evaluation of a unipolar 24V two-channel speed sensor (incre-
mental speed sensor).

Unlike the standard sockets available according to specification RS-422A / RS-485, the
interface is suitable for a 5 V push-pull signal.

The termination resistor of 150 Ω for the speed sensor of the EM-ENC-03 speed sensor
is deactivated by default.

Termination resistor

The termination resistor may only be activated for a 5 V push-pull signal
according to specification RS-422A / RS-485.
For activating the termination resistor, both slide switches S3 must be
set to "ON" position. Setting both slide switches to different positions may
destroy components.
If an unipolar speed sensor is used, e.g. with a 24V signal, no termination
resistor is required.
