Using the keyboard enter ”L” for the subroutine, and
the number of the desired subroutine.

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!
