Undervoltage status
When the DC bus voltage (F18.08) is less than or equal to
the voltage of undervoltage stall control (F07.08), the
current output will be valid; when the DC bus voltage
(F18.08) is greater than or equal to the voltage of power
failure end judgment (F07.10), and the holding time is
greater than or equal to the determined delay time of power
failure end, the current output will be invalid.
25
Motor overheat
pre-alarm
If the current motor temperature (F18.38) is greater than or
equal to the motor overheat pre-alarm threshold (F07.05),
the current output will be valid; otherwise, the output will
be invalid. See the description of the function codes F07.03
to F07.05.
26
Up to the set time
When it reaches the regular running time, the current output
will be valid; otherwise, the output will be invalid. See the
description of the function code F16.09.
27
Running at zero
speed
When the inverter is in the JOG or slave running status and
the output frequency (F18.00) is less than or equal to the
zero servo start frequency (F04.29), the current output will
be valid; otherwise, the current output will be invalid.
28-37 Reserved
38
Off-load
The inverter is in the off-load status.
39-46 Reserved
47
PLC output
When this function is selected for the output terminal, the
output of Y1, Y2, R1, R2 and Y3 will be controlled by the
corresponding bit of F03.31. If the corresponding bit is 1,
the output will be valid; and if the corresponding bit is 0,
the output will be invalid.
59
Sleep indicator
This is dedicated to water supply applications. When the
water pump meeting the sleep conditions is in the sleep
status, the output of this function will be valid.
69
FDT1 lower limit
(pulse)
This is similar to #3/4 function. The difference is that the
output will be valid when the frequency is lower than the
“setting-hysteresis” and automatically turn invalid after
some time. If the single pulse output is set, the time will be
set by F03.17 to F03.20; and if the level output is enabled,
the time is 0.1 s by default.

FDT2 lower limit
(pulse)
71
FDT1 lower limit
(pulse, invalid in
JOG)
This function is the same as #69/70 function, except for no
output in the JOG status.
