Impulse counter

The impulse counter CTR is a small module for registering and processing the output signals of an incremental encoder.

The module comes equipped with a serial interface for programming and sampling of positional information as well as an interface for controlling the unit via the I/O signals of an SPS.

Programming:

The counter module can be controlled and programmed by ASCII-commands transmitted via the serial interface (see table below).

An SPS interface enables the module to be controlled via external I/O signals.
