■
Count the run time of commercial power-driven motor 1, 2 – “CRUN-M1, 2” (E01 to E05, data = 72, 73)
Even when a motor is driven by commercial power, not by the inverter, it is possible to count the cumulative motor
run time 1, 2 (H94, A51) 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
5_23
on Menu #5 “Maintenance Information” of the keypad.
H79 Preset startup count for maintenance (M1)
Related function codes: H44 Startup count for motor 1
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 (FFFF in hexadecimal.)
• Data setting range: OFF (disable), 0001 to FFFF (hexadecimal)
■
Maintenance timer counted up – “MNT” (E20, E21 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 inform 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 key to reset the output signal and restart counting.
This function is exclusively applied to the 1st motor.
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.
