H74 Torque limiter (Control target)
Refer to F40, F41.
H76 Torque limiter (Braking) (Frequency rising limiter for braking) (refer to H69)
For details, refer to the description of H69.
H77 Service life of DC link bus capacitor (Remaining time)
Indicates the time remaining (in units of ten hours) before the end of service life of the DC link bus capacitor.
Transfer the DC link bus capacitor life data when replacing the printed circuit board.
• Data setting range: 0 to 8760 (in units of 10 hours 0 to 87,600 hours)
H78
H94
Maintenance interval (M1)
Cumulative motor run time 1
Specify the maintenance interval in hours with the maintenance interval (M1) (H78).
Specify in units of 10 hours. Up to 9999 x 10 hours can be specified.
• Data setting range: 0 (disable), 1 to 9999 (in units of 10 hours)
■
Maintenance timer counted up – “MNT” (E20, E21 and E27, data = 84)
When the cumulative motor run time 1 (H94) reaches the value specified by the maintenance interval (H78), the
inverter outputs the maintenance timer signal “MNT”.
■
Cumulative motor run time 1 (H94)
The cumulative run time of the motor can be indicated by keypad operation. It can be used for management of the
machinery or maintenance. Specifying an arbitrary time for the cumulative motor run time 1 (H94) allows an
arbitrary value to be specified for the cumulative motor run time. It can be replaced with the initial data to use as a
guide for the replacement of machine parts or inverter. Setting “0” allows the cumulative motor run time to be reset.
<For half yearly maintenance>
If the maintenance interval is reached, set a new value in H78 and press the key to reset the output
signal and restart measurement.
This function is exclusively applied to the 1st motor.
