Operate the ”PART PROGRAM”, ”DIRECTORY” and
”SUBROUTINE” softkeys, one after the other, in any of
the operating modes:
PRESET / JOG / AUTOMATIC /
INC 1 .... INC 10 000 / REFPOINT.
Using the keyboard enter ”L” for the subroutine, and
the number of the desired subroutine.
Now operate the ”ENABLE” softkey.
The cycle is entered in the list of (unprotected) subroutines.

Sequence of operation
Cancelling the cycle lock for cycles stored in the
EPROM depends on the PLC program. The cycles can
be protected against unauthorised output by
programming the PLC accordingly.
This effectively protects the machine tool manufacturer's or user's knowhow.
It is then no longer possible for the operator to enable and disable programs!
