If the frequencies for AP2-02 (Low Freq) and AP2-08 (High Freq) are set too close to each other,
the resulting load curve may not reflect the actual (ideal) load curve. Therefore, it is recommended
that you keep the AP2-02 and AP2-08 frequencies as close to the factory defaults as possible.
•
If a secondary motor is in use, note that the existing load curve for the main motor will be applied
to the secondary motor unless a load tuning has been performed for the secondary motor.

Level Detection
When the inverter is operating at or above the frequency set at PRT-74 (
LDT Level
)
, this function is
used to triggers a fault trip or sets a relay output if the source value is out of the range of the user-
defined values. If the reset restart feature is turned on, the inverter continues to operate based on
the run command after the LDT fault trip is released.
