L8-18 Soft CLA Selection
Setting
0
Disabled
1
Enabled (factory default)
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).
