The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 156)
*1 Pr. 129, Pr. 130, Pr. 133 and Pr. 134 can be set during operation. They can also be set independently of the operation mode.

The inverter stops operation if the output frequency after
0 to 3600s PID operation remains at less than the Pr. 576 setting for
longer than the time set in Pr. 575.

Set the frequency at which the output interruption
0 to 400Hz
processing is performed.
Set the level (Pr. 577 minus 1000%) to release the PID
output interruption function.
