5.4 Details of Function Codes
5-202
Input during commercial running (motor 1 to 4) CRUN-M1 to 4 (Function code E01 to E09 data = 72 to 75)
Even when a motor is driven by commercial power, not by the inverter, it is possible to count the motor
cumulative run time 1 to 4 (H94, A51, b51, r51) by detecting the ON/OFF state of the auxiliary contact of the
magnetic contactor for switching to the commercial power line.
Check the motor cumulative run time with
5_23
on "Maintenance Information" of the keypad.
H79
Maintenance Setting Start Count (M1) Related Function Code: H44 Startup Count 1
H79 sets 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: 0000 (Disable) 0001 to FFFF (Hexadecimal)
Maintenance timer MNT (Function code E20 to E24, E27 data = 84)
When the startup number 1 (H44) reaches the value set by the maintenance set startup count (H79), the
maintenance call signal
MNP is output.
< Maintenance every 1,000 times of startups >
Fig. 5.4-89
If the startup counter reaches the specified value, set a new value for the next maintenance in H79
again and press the
key to reset the output signal and restart counting.
This function is exclusively applied to the 1st motor.
H80
Current Fluctuation Damping Gain 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 0.40 s (ROM version earlier than 2000)
0.00 to 1.00 s (ROM version 2000 or later)
