24 Hour Time Clock
Optidrive P2 includes a 24 hour time clock, accessible through the Function Block Editor. This allows time based functions to be realised. The
accuracy of the clock varies between drives, and a function is included to allow fine tuning of the timer function. The internal time value may
be read from or written to within the function block editor.
Note that the value is not retained during power off.

24 Hour Timer Trim Adjustment
The internal 24 volt timer includes a trim function, adjusted as follwos :-
With the drive in display showing “Stop” or “Inhibit”, press and hold the Up and Down keypad keys for >1s
The display will show the present timer value in hours and minutes as xxhxx, and can be adjusted if desired using the Up and Down keys.
Following setting of the desired time, press the Navigate button
The display will now show the timer trim value percentage, displayed as “t0.00”. This can be adjusted using the Up and Down keys to a
maximum of + / - 3.00%
Press the Navigate key to exit the trim adjustment
Press the Up and Down keys together to exit the timer adjustment, or alternatively, press the Stop key to exit without saving.
If the internal 24 hour timer operates faster than is correct, a positive trim value is required. The trim value can be checked by leaving the drive
powered over 24 hours and checking the timer value. The correct trim setting should be Error Minutes / Total Minutes, where Error Minutes is
the difference between the drive displayed minutes and the actual minuts that have elapsed.
