52 • Operation Theorem
The encoder error interrupt is provided to detect abnormal situation.
Simultaneously changing of EA and EB signals will cause an encoder error.
If bit #14 of the interrupt factor register (INT factor) is set as 1, the IRQ will
be generated when detect encoder error during operation.
The index inputs (EZ) signals of the encoders are used as the “ZERO”
index. This signal is common on most of the rotational motors. EZ can be
used to define the absolute position of the mechanism. The input logic
polarity of the EZ signals is programmable by software function
set_home_config(). The EZ signals status of the four axis can be
monitored by get_io_status().
