Local Keypad Battery Low (L75) is set to one when a keypad is installed to the front of the drive with an internal real-time clock and the battery is not
installed or the voltage is below the minimum threshold.
Remote Keypad Battery Low (L76) is set to one when a keypad is connected to the drive user comms port with an internal real-time clock and the
battery is not installed or the voltage is below the minimum threshold.
Defaults Previously Loaded (L77) shows the value used to load the previously loaded defaults (i.e. 1233 for 50 Hz defaults, or 1244 for 60 Hz
defaults).
