motor. The up/down counter counts up when the phase of EA sig-

nal leads the phase of EB signal.

The following diagram shows the waveform.

The index input (EZ) signals of the encoders are used as the

“ZERO” reference. This signal is common on most rotational

motors. EZ can be used to define the absolute position of the

mechanism. The input logic polarity of the EZ signals is program-

mable using software function HSL_M_set_home_config(). The

EZ signals status of the four axes can be monitored by

get_io_status().

The feedback position counter will be automatically cleared to “0”

after a home move is complete. Besides setting a position with the

function call, HSL_M_set_position(), it can also be executed at

any time to set a new position value. To read the current command

position use HSL_M_get_position().
