38 Appx.1: Setting the System Lock
38.3 Display of Time Limit Warning and Alarm Notification
(1) When the indication period of warning is reached, the warning "Z64 Valid term soon to be expired" appears at the
bottom right of the screen.
This warning appears at every cycle start after power ON until the expiry date comes. Cycle start operation can be
performed before the warning and alarm indication reference time of the expiration date.
(2) If the warning and alarm indication reference time of the expiration date have passed, the alarm message "Z65
Valid term has been expired" appears, which disables cycle start operation. This alarm cannot be canceled with
reset. Instead, enter the decryption code issued by a machine tool builder, and then turn OFF and ON the CNC
power.
If the expiry date is over during a cycle start operation, the operation continues until automatic operation pause,
block stop or reset is input.
If the expiry date is over during a cycle start operation and automatic operation or block stop occurred, cycle start
operation cannot be performed.
38.4 Caution
(1) The system lock function is enabled by setting an encryption key and an expiration date while the system lock is
disabled. Be careful that the date and time of the CNC cannot be set both to a past and to a future from the
expiration date while the system lock is enabled.
When you advance date and time to the expiration date, set "#1724 cfg24/bit2" (System lock date and time setting
permission) to "1". This parameter is set to "0" when the power is turned ON or at the cycle start.
(2) MTBs need to manage the encryption dedicated tool and the encryption key not to be leaked to the users. The
encryption key file must be created on a PC.
(3) If you turn OFF and ON the power after the time limit has expired, "EMG Emergency stop LINE" may appear at the
same time.
(4) When the clock data is incorrect without a battery backup, the automatic start cannot be performed. Exchange the
battery and set the current date and time.
(5) If you upgrade the M8 Series software version from C3 or older to C4, perform the upgrading work after canceling
system lock.
(6) When you upgrade the M8 Series software version from C3 or older to C5 or later with system lock enabled, the
password for the system lock is automatically expanded to 8 digits. To issue a decryption code, add "0000" to the
head of the conventional encryption key. Moreover, use the "System Lock Pass Code Maker" (BND-2201W000-A0
or later) to issue the decryption code.
(7) When you downgrade the M8 Series software version from C4 or later to C3 or older, you cannot perform the
downgrade work with system lock enabled. To downgrade from version C4 or later to version C3 or older, cancel
system lock and then perform the downgrade work.
(8) When you temporarily disable the system lock function in version D6 or earlier of M8 CNC, set a past date and time
on the integrated time screen, and then reset the expiration date, the expiration date may be set to "1970.1.1".
The expiration date will be set correctly following the procedure below.
(a) Disable the System lock function.
(b) Update the CNC to S/W version D7 or later.
(c)
Set the expiration date.
(d) Turn the CNC power ON.
