532 Fault Variables
The number of pointers a program stack can contain (“program stack
depth”) varies by controller, as follows:
The Stack Fault occurs when:
the number of program calls to the stack exceeds the program stack
depth, or
the number of returns exceeds the number of calls from the iCODE
script to the program stack.
The effect of this fault on program execution is the same as issuing a Stop
command. When this fault occurs:
program execution halts,
motion on all axes stops at 100% of Maximum Deceleration, and
Feedback remains enabled.
GML Commander displays a message identifying the name of the
function block and the module that triggered the fault.
To correct the problem:
1. Check the block and module referenced in the error message.
2. If the referenced block precedes a Native Code block, the problem
may be iCODE corruption. If so, correct any obvious iCODE errors
in the Native Code block.
