Incremental Encoder Interface with Differential Input
This terminal is an interface for direct connection of incremental encoders with differential inputs (RS422). A 16-bit counter (in normal operating mode) or a switchable 16/32-bit counter (in enhanced operating mode) with a quadrature decoder and a 16-bit latch (in normal operating mode) or 32-bit latch (in enhanced operating mode) for the zero pulse can be read, set or enabled. Incremental encoders with alarm output can be connected at the negative switching status input of the interface. The measurement of period and frequency is possible. The gate input allows the locking of the counter, alternatively with a high or low level. The latch input is similarly configurable and evaluates high or low levels. The AKT2G-ENC-190-000 can also be used as bidirectional counter on channel A; channel B specifies the count direction.
