3-7-4 Low Load Detection Parameters
The following parameters work in con-
junction with the intelligent output func-
tion, when configured. The output
mode parameter (C038) sets the mode
of the detection at which the low load
detection signal [LOC] turns ON. Two
kinds of modes can be selected. The
detection level parameter (C039) is to
set the level of the low load.
This function is for generating an early
warning logic output, without causing
either a trip event or a restriction of the
motor current (those effects are available on other functions).
3-7-5 Output Function Adjustment Parameters
Overload Warning Output - The fol-
lowing parameters work in conjunction
with the intelligent output function,
when configured. The overload level
parameter (C041) sets the motor cur-
rent level at which the overload signal
[OL] turns ON. The range of setting is
from 0% to 200% of the rated current
for the inverter. This function is for gen-
erating an early warning logic output,
without causing either a trip event or a
restriction of the motor current (those
effects are available on other functions).
Frequency Arrival Output - The fre-
quency arrival signal, [FA1] or [FA2], is
intended to indicate when the inverter
output has reached (arrived at) the tar-
get frequency. You can adjust the timing
of the leading and trailing edges of the
signal via two parameters specified to
acceleration ad deceleration ramps,
C042 and C043. Refer also to
SECTION 4 Operations and Monitoring on page 165.
