which need to be continuously updated. (Refer to each function block for more detail).
- Input value exceeds range
When a motion control function block is enabled, the system restricts you to input values that exceeds the
permitted range. Nevertheless, error occurs during execution of motion control function blocks and results in
motion axes errors. You should avoid input incorrect values in programs.
- Output pins are mutually exclusive.
▓
When a function block contains Execute input, Busy output, Done output, CommandAborted output or
Error output, only one state is set to True during the same time. When Execute input is set True, one output
(Busy, Done, CommandAborted or Error) must set True.
▓
When a function block contains Enable input, while Valid output and Error output are mutually exclusive,
this indicates only one output is set True.
- Valid time for output data/status value
▓
When a function block contains Execute input and the input signal changes from True to False, the current
Done output, Error output, CommandAborted output of current True and output pin data are reset or cleared.
However, when a function block is Busy, despite that the Execute input signal changes from True to False,
execution of the function block will not stop. The expected output state (Done output, Error output,
CommandAborted output) will generate to True and retain for one week.
▓
When a function block contains Enable input and input signal changes from True to False, Valid output,
Busy output and Error output are reset. (For input and output description not mentioned, please refer to
MC_Power instruction for more details.)
- Characteristic of Done output
When execution of a motion control function block is completed, Done output is set to True.
- Characteristic of Busy output
▓
When a function block contains Execute input and uses Buy output to indicate incomplete execution, new
output state (value) is to be generated. When Execute input signal changes from False to True, then Busy
output is set to True. When Done output, CommandAborted output or Error output is set to True, then Busy
output is reset.
▓
When a function block contains Enable input and uses Buy output to indicate incomplete execution, new
output state (value) is to be generated. When Enable input signal changes from False to True and as long as
Busy output is set True, changes in input state (value) can be expected.
- Characteristic of CommandAborted/Aborted output
When execution of a motion control function block is aborted, CommandAborted/Aborted output is set True.
- Relation between Enable input and Valid output
A function block contains Enable input and uses Valid output to indicate validity of output data/status. Only when
Enable input is set True and output data/status is valid, then Valid output is set True; when errors occur in function
blocks, then output data/status is invalid and Valid output is set to False; when errors are cleared in motion control
function blocks and output data/status changes to valid, then Valid output is set to True.
