3) Inverter overload characteristics

Set to protect the inverter unit. Cannot be turned off by parameter setting.

The inverter has two overload detecting functions, which can be switched fr om one to another using parameter

H (temperature detection).

[Parameter setting]

Title Function Adjustment range Default setting

H Temperature detection :Standard (150%-60 sec.)

: Estimation of temperature 

If the inverter overload trip function (QN) is activated frequently, this can be i mproved by adjusting the stall

operation level H downward or increasing the acceleration time CEE or deceleration time FGE.

Inverter overload protection characteristics

Note 1: If the load applied to the inverter exceeds 150% of its rated load or t he operation frequency is less than

0.1Hz, the inverter may trip (QN or QER~QER) in a shorter time.

Note 2: The inverter is factory-set so that, if the inverter becomes overl oaded, it will automatically reduce the

carrier frequency to avoid an overload trip (QN or QER~QER). A reduction in carrier freque ncy

causes an increase in noise from the motor, but this does not affect the performance of the inverter.

If you do not want the inverter to reduce the carrier frequency automati cally, set the parameter

H=.

Note 3: Overload detection level is variable by condition of output frequen cy and carrier frequency.
