KL5101

Incremental encoder interface

The KL5101/KS5101 terminal is an interface for direct connection of incremental encoders with difference signal (RS422) or single inputs. A 16-bit counter with a quadrature decoder and a 16-bit latch for the zero pulse can be read, set or enabled. Incremental encoders with alarm outputs can be connected at the interface's status input. Period duration measurement with a resolution of 200 ns is possible. The G2 input allows the counter to be halted (high = stop), and the value is read with a positive edge at G1.
