1-channel incremental encoder interface, 32 bit

Incremental Encoder Interface AKT2G-ENC-180

The AKT2G-ENC-180 EtherCAT Terminal is an interface with 24 V inputs for the direct connection of incremental encoders. A 32 bit counter with a quadrature decoder and a 32 bit latch for the zero pulse can be read, set or enabled.

The measurement of period and frequency is possible. The gate input allows the locking of the counter, selectively with a high or low level. The latch input is similarly configurable and evaluates high or low levels.

The AKT2G-ENC-180 supports distributed clocks, i.e. the input data can be synchronously acquired with other data that are similarly connected, distributed to distributed clock terminals. The universal system accuracy is around < 100 ns.

With a moving axis, the micro-increment functionality offers 256 times higher axis position resolution than physically provided by the encoder.

The AKT2G-ENC-180 can also be used as a single-channel 32/16 bit counter on channel A, in which case the signal level on channel B defines the count direction.
