POSx_DIS Instruction
The POSx_DIS instruction turns the DIS output of the
Position module on or off. This allows you to use the DIS
output for disabling or enabling a motor controller. If you use
the DIS output on the Position module, then this instruction
can be called every scan or only when you need to change
the value of the DIS output.
When the EN bit turns on to enable the instruction, the
DIS_ON parameter controls the DIS output of the Position
module. For more information about the DIS output, see
Table 9-8 or refer to the specifications for the Position
module in Appendix A.
The Error parameter contains the result of this instruction.
See Table 9-20 for definitions of the error codes.
