5. Program example
1) Circuit diagram
In the sequence circuit shown below, all areas except shaded areas are standard.
Program the shaded areas according to the contents of control.
a) Initial circuit
While the machine is operating, the operation mode can be switched arbitrarily (among stepping
operation, cycle operation and continuous operation) in the automatic mode.
When the operation mode is switched among the individual operation mode, zero return operation
mode and automatic mode while the machine is operating, all outputs are reset once to assure safety.
And then the mode after switching becomes valid.
(While M8045 (All output reset disable) is ON, outputs are not reset at all.)
b) Individual operation mode
Programming is not required when the individual operation mode is not provided.
