H77
Service Life of Main Circuit Capacitor (Remaining time)
H77 displays the remaining time before the service life of main circuit capacitor expires in units of ten hours.
At the time of a printed circuit board replacement, transfer the service life data of the main circuit capacitor to
the new board.
- Data setting range: 0 to 8760 (in units of ten hours, 0 to 87,600 hours)
H78
H94
Maintenance Setting Time (M1)
Motor Cumulative Run Time 1
H78 sets the maintenance interval (M1) (H78) in units of ten hours.
The maximum setting is 9999 x 10 hours in units of 10 hours.
- Data setting range: 0 (Disable) 1 to 9999 (in units of ten hours)
Maintenance timer MNT (Function code: E20 to E24 and E27, data = 84)
When Motor Cumulative Run Time 1 (H94) reaches the set maintenance set time (H78), the signal to start
the maintenance
MNT is output.
Motor Cumulative Run Time 1 (H94)
Operating the keypad can display the motor cumulative run time. This feature is useful for management and
maintenance of the machinery. When the desired time is set to motor cumulative run time 1 (H94), the motor
cumulative run time can be set to desired value. Rewriting to the initial data that is used as a target for the
machine parts and inverter is possible. Specifying "0" clears the motor cumulative run time.

If the maintenance interval counter reaches the specified value, set a new value for the next
maintenance in H78 and press the
key to reset the output signal and restart counting.
This function is exclusively applied to the 1st motor.
