(0 - 3)
The drive saves parameter settings to the keypad at these times:
1. After you energize the drive and the auto backup period passes.
2. When you use ROM enter or the keypad to change parameters, the drive saves those changes in the drive,
waits for the auto backup period to pass, then saves those parameters in the keypad.
NOTICE: Think about this limit when you set the auto backup period. You can write data to the keypad a maximum of 100,000
times. If you write data to the keypad more than 100,000 times, it can cause data access errors and keypad failure.
