Operation Theory
The following diagram illustrates 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
_8164_set_home_config()
.
The EZ signals status of the four axes can be monitored by
get_io_status()
.
The feedback position counter is automatically cleared to
0
after a
home move is complete. Besides setting a position with the func-
tion call,
_8164_set_position()
, it can also be executed at
any time to set a new position value. To read the current command
position use
_8164_get_position()
.
