F0.20 Reserve
Functional Details 38
F0.21 Parameter password protection Setting range: 0000 ~ 9999
F0.22 UP/DW speed
Setting range: 0.1~50.0Hz
When [F0.00]=5, [F1.28]=9 or 10, and input terminal selects UP or DW function,
frequency can be set through external terminals. This parameter is used to set the
increasing and decreasing speed of the frequency set by external terminal.
6.2 analog input output parameter group
The function parameter group [F1.00] ~ [F1.01 defines the
upper and lower limit of external input signal as the frequency
setting signal. E550 series inverters allow for inputting analog
voltage signal and analog current signal; the analog current
signal 0-20mA is corresponding to the voltage signal 0-10V.
F1.00 AI input lower limiting voltage
Setting range: 0.0V ~ [F1.01]
F1.01 AI input upper limiting voltage
Setting range: [F1.00] ~ 10.0 V
[F1.00] and [F1.01] defines AI range of analog input channel, which shall be set according
to actual conditions of access signal.
F1.02 AI input filter time
Setting range: 0.01 ~ 1.00Sec
When external analog input quantity is subject to filter processing to effectively
eliminate interfering signals, if it is set to large value, the interfering capability is
strong but it will slow down response speed to setting signals.
