output
Please refer to the instruction of function code Fb-23, Fb-24.
12
Zero speed running
1 (no output when
stop)
When frequency inverter is running and the output frequency is 0,
then output ON signal. When inverter is in a state of downtime,
the signal is OFF.
13
Zero speed running
2 (output when
stop)
When frequency inverter is running and the output frequency is 0,
then output ON signal. When inverter is in a state of downtime,
the signal also is ON.
14
Frequency upper
limit reached
When operation frequency reach to the upper limit frequency,
output ON signal.
15
Frequency lower
limit reached (about
running)
When operation frequency reach to the lower limit frequency,
output ON signal. When inverter is in a state of downtime, the
signal is OFF.
16
Frequency lower
limit reached (output
when stop)
When operation frequency reach to the lower limit frequency,
output ON signal. When inverter is in a state of downtime, the
signal also is ON.
