Controlword Status
When a Fault Reset is executed with bit 7, set the bit back to 0 before giving the next command.
The bit configuration of the External Output variable is given in the following table.
Note You can assign the External Output object to I/O data to control its ON/OFF state. However, when the Unit
is assigned to an MC Function Module axis and the External Output 0 Function Selection parameter is set
to Error counter reset, the external output is controlled automatically through the latch function. You cannot
turn it ON and OFF directly.
