L8-18 Soft CLA Selection

The Soft CLA (software current limit level) is a Drive protection function that will limit the Drive’s output current. The Drive 
limits the output current by reducing the output frequency whenever the current exceeds 110% of the inverter rated    current If 
the current level drops below the Soft CLA level, then normal operation will continue.  

If the software current limit is disabled (L8-18= “0: Disabled”), the Drive may trip on an OC fault if the load is prohibitively 
large or the acceleration is too short. For proper Drive protection and operation leave the Soft CLA function enabled.

L8-19 Overheat Frequency Reference Reduction Level

Setting Range:

0.0 to 100.0% of maximum frequency

Factory Default: 20.0% of maximum frequency

When the heatsink temperature reaches the OH Pre-alarm level (L8-02) and the Overheat Pre-Alarm Operation Selection     
parameter is set for Alarm and Reduce (L8-03= “4: OH Alarm & Reduce”), the L8-19 parameter sets the amount of speed 
decrease that will be applied to the Speed Command in order to lower the heatsink temperature.  The decrease in speed will    
lower the current being switched and conducted by the heat producing output transistors of the Drive.

Parameter L8-19 is set in percentage of maximum frequency (E1-04).
