The Machine Controller operation must be stopped when this operation is executed. The basic control
cycle will not return to its default value when Machine Controller memory is cleared. The power sup-
ply must be turned OFF and then back ON to return the basic control cycle to the default value.
„ Compressing Memory
If the user program becomes too large and the available user program memory is reduced,
then the user program memory will become fragmented when the program is repeatedly
changed. If that occurs, it may become impossible to make changes or additions to the pro-
gram even if the required memory capacity is available. By executing the memory compres-
sion operation, the utilized area in the user program memory will be packed and the
fragmented area will be repaired.
1. Select Control (C) and then MEM COMPACT (L) from the menu.
2. Click the Yes Button in the message box.
By using memory compression, programs can be created up to the limit of the user program memory.
When the user program memory is full, however, existing programs cannot be changed.
