H : Cumulative operation time alarm setting
• Function
This parameter is to make a setting so that the inverter puts out a signal when its cumulative operation time
has reached the time set with H.
* Indication of  represents 10 hours. Ex.: If  is displayed, the cu mulative operation time is 3850 hours.

• Function
When use at speed control mode with sensor (RV=, ), it always monitors the rotational speed of the
motor, even when the motor is at rest, and if the speed remains out of the specified limits for the specified
length of time, it outputs an error signal.
When use at speed control mode without sensor (RV=~), it always monitors the estimated rotational
speed of the motor.
