: 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 ￿￿￿￿.

* Indication of ￿￿ represents 10 hours. Ex.: If ￿￿￿ is displayed, the cumulative operation time is 3850 hours.

:Overspeed detection frequency upper band

:Overspeed detection frequency lower band

•Function

When use at speed control mode with sensor (￿￿=￿, ￿), 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 (￿￿=￿~￿), it always monitors the estimated rotational speed of the motor.

Note 1: This function doesn't operate at the time of a torque control. !

Note 2: It is advisable to set the parameter ￿￿￿￿ (Acceleration/deceleration operation after torque limit) to ￿ when this function is set.
