The FlexDrive
follow a master encoder or pulse and direction inputs. An interface for a three-channel,
incremental encoder (CHA, CHB, CHZ) is provided. The input receiver circuit allows only
encoders with differential line drivers (RS422) to be used. The interface also provides an
isolated 5V supply for the encoder electronics, capable of driving up to 100mA.
CAUTION: The master encoder input does not use the same pin configuration as
'X3' FlexDrive
