AC70 VC CONTROL FREQUENCY INVERTER MANUAL
FUNCTION PARAMETER DETAILED SPECIFICATION
101
F-33
Frequency arriving detect bias
Range: 0.00-50.00Hz
Default: 1.00 Hz
F-34
Output frequency level detection
Range: 0.00-600.0Hz
Default:30.00 Hz
F-35
Output frequency level detecting
relay time
Range: 0.0-20.0s
Default: 0.0s
When output frequency approaches or close to frequency reference given value, output terminal outputs signal.
[F-33]
function uses to adjust the bias of the detection amplitude.
Output frequency level detection:
Uses it to program the frequency detection level, when the output frequency
high
[F-34]
setting value, output terminal will output signal after
[F-35]
setting relay time. When the output
78frequency low to than
[F-34]
setting value, output terminal will stop output signal after
[F-35]
setting relay time.
F-36
Overload pre-alarm level
Range: 50%-200%
Default: 150%
F-37
Overload pre-alarm delay time
Range: 0.0-20.0s
Range: 1.0s
If the output current continues to be over the setting level of the parameter
[F-36]
, after the delay time
[F-37]
, the
output terminal outputs valid signal. In the same way, when the output current is lower than the setting level of
[F-36]
,after the delay time
[F-37]
, the output terminal outputs invalid signal.

F-38 Timer setting value
Range: 1-65000s
Default: 1s
This parameter is used to timing for the frequency inverter. The timer start-up is activated by the external trigger
terminal of the timer
（
trigger terminal is selected by
[F-01-F06]
）
. Timing from receiving the external trigger signal,
while reaching the timed time, it outputs a width is 1 second pulse signal by the corresponding output terminal.
If the external trigger signal always locate trigger condition, the corresponding terminal outputs a pulse signal every
[F-38]
setting time.
