4 DIFFERENCES IN SEQUENCE OPERATION
This section describes the differences in sequence operation.
4.1 Stall Memory
Stall memory is a function to memorize the control output at the moment when the operation/stop command has changed
from operation to stop. In unwinding and winding control, in case the system stops while the material on the reel shaft is not
completely finished, the control output at the moment the system makes a stop is memorized. When it restarts, automatic
control can be continued with the stored control output as stall output.
Differences in operation
When LE-30CTN(A) is used
The term output memory used in LE-30CTN(A) has been changed to stall memory in LE7-40GU-L (the sequence operation
remains unchanged). In the LE-30CTN(A) there is no setting parameter called stall setting and the control output at stop is
manual 1. By entering the same setting % as LE-30CTN(A) 's manual 1 in the stall setting of LE7-40GU-L, the same output
operation can be performed as in the LE-30CTN(A).
