Function Library
14 EA/EB, PA/PB encoder input error
15 start with STA signal
16 Completion of acceleration
17 Start of deceleration
18~22 Should be Set to 0
23 RDY active (AP3 of PCL5023 change from 1 to 0)
24~31 Should be set to 0
Note: Bit 14: The interrupt is generated when pins EA and EB, or PA
and PB change simultaneously. It means there has an encoder input
error.
get_int_axis:
This function allows user to identify which axis generates the INT
signal to host PC. (
This function is for DOS only )
get_int_status:
This function allows user to identify what kinds of interrupt is
generated.
After user gets this value, the status register will be cleared to 0. The
return value is a 32 bits unsigned integer and the definition for each
bit is as following:
Bit Interrupt Type
0 Stop with the +EL signal
1 Stop with the –EL signal
2 Stop with the +SD signal
3 Stop with the –SD signal
4 Stop with the ALM signal
5 Stop with the STP signal
6 Comparator Active
7 Always 0
8 Stop with v_stop() command
9 Stop with home return completed
10 Always 0
11 Stop with preset movement completed
12 Stop with EA/EB input error
13 Always 0
14 Stop with PA/PB input error
15 Start with STA signal
16 Acceleration Completed
17 Deceleration Started
18~22 Always 0
23 RDY active(AP3 of PCL5023 change from 1 to 0)
24~31 Always 0
