e.g., for replacement of a belt.
Set the H79 and H44 data in hexadecimal. The maximum setting count is 65,535 (FFFF in
hexadecimal.)

When the count of the startup counter for motor 1 (H44) reaches the number specified by H79
(Preset startup count for maintenance (M1)), the inverter outputs the maintenance timer
signal MNT (if assigned to any digital terminal with any to E20 and E27) to remind the user
of the need of the maintenance of the mechanical system.
