 Count the run time of commercial power-driven motor 1 -- CRUN-M1
(E01 to E07, data = 72)
Even when a motor is driven by commercial power, not by the inverter, it is possible to count
the cumulative motor run time 1 (H94) by detecting the ON/OFF state of the auxiliary contact
of the magnetic contactor for switching to the commercial power line.
Check the cumulative motor run time with PRG > 3(INV Info) > 4(Maintenance)
on the keypad.
H79
Preset Startup Count for Maintenance (M1)
H79 specifies the number of inverter startup times to determine the next maintenance timing,
e.g., for replacement of a belt.
Set the H79 and H44 data in hexadecimal. The maximum setting count is 65,535.
- Data setting range: OFF (Disable), 1 to 65,535
 Maintenance timer -- MNT (E20 to E24 and E27, data = 84)
When 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 to E24 and E27) to remind the user of the
need of the maintenance of the machinery.
< Maintenance every 1,000 times of startups >
If the startup counter reaches the specified value, set a new value for the next
maintenance in H79 and press the
counting. This function is exclusively applied to motor 1.
H80
Output Current Fluctuation Damping Gain for Motor 1
The inverter output current driving the motor may fluctuate due to the motor characteristics
and/or backlash in the machinery (load). Modifying the H80 data adjusts the controls in order
to suppress such fluctuation. However, as incorrect setting of this gain may cause larger
current fluctuation, do not modify the default setting unless it is necessary.
- Data setting range: 0.00 to 1.00
